Lyszko the jews as a group have been doing this since roman times... They assimate into a country, learn the langauge and customs, set up businesses or go to the local uni to become a doctor, lawyer, businessman, politician. In cases of the powerful upper echelons of the learned Jews this is merely a smoke screen - whether they had to learn French or German it makes little difference. Some Jews will only interact with other jews as Jewish scripture states, but of course not all follow this tenet due population growth, technology, etc. However some of the Jewish community especially the more orthodox tend to keep to their own. Often times marraiges are arranged and the rules of day to day living are very strict. Yet, some of the younger practicing orthodox do drugs because they argue there's nothing in their scripture restricting their use. One issue of these arranged marriages within such a small community can result in inbreeding. For example, tay Sachs disease is essentially unique to the Jewish community. Doctors recommend couples get tested prior to having kids to make sure they're compatible due to the issues of inbreeding.
The practice of dissociation from society would've surely been more prevalent during Babylonian or Egyptian captivity to avoid infiltration and the wrong info getting out but the practice is waning. Ive eaten at plenty of Israeli delis in hardcore Jewish areas and the worst that happens is just stares which I interpret as 'what is that pretty Jewish girl doing with that crude goy!? Oy vey..' sometimes a table will speak in a foreign language to make fun of me or my gf in Yiddish or hebrew. My gf will tell me what they said and I promptly walk over to their table, put my hands on the top of the table, look them in their eyes and ask them if they have the balls to repeat what they said in english. Ill usually say something along the lines of 'what's a matter did doc screw up and snip off your balls too' Meanwhile Ill help myself to a bite or two of some of their finger food, use a napkin laying on their table and throw it square in the middle of their plate while they fathom what's going on. Afterall, these guys aren't use to be calling out on their b.a. after about 1 min theyre so scared and say sorry sorry sorry I'm so sorry what can I do to make it up. I tell them sorry isn't going to cut it as you've offended my woman and I won't tolerate that. I stand in such a way they can't really move out their booth. They apologize profusely and sometimes I get a free meal for two or like $50 out of it. Hey I didn't start it and had no intention of fighting but perhaps now they'll learn to talk $hit about people willingly spending money in a Jewish kosher establishment despite being catholic simply because I am interested in all cultures.
Anyway in more modern times jews became fluent in German French english or wherever they settled for a longer period of time than their ancestors. Keep in mind the jews/Israelis have always been on the move bouncing from place to place throughout their entire history - egypt, babylon, rome, judea, england, spain' germany, switzerland, poland, and hundreds more if you're counting countries, states, principalities, etc as the world was shaped from the end of the Roman empire to the tail end of the collapse of feudalism. The jews have migrated through the world far far more than gypsies. The gypsies moved out of India to Europe and for the most part stayed there with a few moving to north America in more recent times. Yet I can't think of dozens upon dozens of edicts expelling Roma (gypsies) from the monarchs realm. Not the jews though - over 115 places they were kicked out of over 2'000 years. Literally there are a total of 115 to 140 different city-states, countries, principalities, kingdoms, etc that have all issued edicts to expel the jews from their respective realm over the past 2000 years. Could it be racism? Perhaps. I think the more likely cause is that the townsfolk complained to their leaders that the jews were usurping them and creating monopilies, destroying businesses, causing people to lose homes because they can't make the payments etc etc.
Nonetheless, the bottom line is the very same group of people were kicked out of over 115 city states, principalities, and countries - spanning 3 continents, over the course of 2,000 years. Itd be foolish to think that it was always fault of all the 115 city states and not the jews. The gypsies are to this day known as thieves, tarot card readers, pick pockets, scammers, etc yet there's no case of over 100 countries and city states exiling them.
I could attribute perhaps 2 incidents maybe 5 or 10 where a ruler kicked out the jews but that's not the case - rulers from all over western, central and eastern Europe as well as Africa and Asia all kicked out the jews. One can cry Racist! Antisemite! If there were say one state, or even dozen or two dozen that kicked out the jews. But no its over 100 states that have (including one of the us colonies actually attempted this) kicked out the jews from their realm, oftentimes after welcoming them in because the next door neighbor state kicked them out, over the course of 2000 years.. There's obviously more to this and I believe it has to do a lot with those who practice Talmudic writings into everyday light. I've read a good portion of the Talmud (7k pages in total) but read the sanhedrin front to back... The things I can tell you that are in there are rsther shocking. Certain passages in the Talmud make Hitler's MeIN Kampf look like Snow White and The Seven Dwarfs.
but they do not abandon their menorah nor their Hebrew language and most importantly the Torah and Talmud teaching learned in the yeshiva. Similar to the current migrants in the special urban zones SEZ the French fall them I believe (no go zones), the jews too have their own areas that are 90% plus Jewish. One in particular is Kiryas Joel which you can look up. The difference is in Kiryas Joel while a goy may get some strange looks, he probably won't get accosted, threatened, or just generally feel unsafe. However it is advisable for women who travel through to wear a head scarf, a long skirt, and unraveling neckline or teenagers may throw rocks at her.
The Talmud writes much on this topic as a good portion of it was written while the jews were living in exile under the babylonians. It taught the jews to smile and be friendly to the locals, adapt to their culture, learn their language, but deep inside have a hatred for them because they conquered their kingdom and still view them as non Jewish cattle aka goyim. For example, a specific passage states its permissible to kick a ladder that a goy may be standing on while another says if a goy loses money and a jew finds it a jew may keep it but if a jew loses money a jew must return it if its found. Other examples state its totally fine to usurp a goy but not a jew.
However by far the most offensive thing I read in the talmud is a passage that states Mary (Miriam) was a wealthy governesses' daughter who wh0red and slummed it with a carpenter. The result was Jesus (Yashu) which explicitly states that Jesus is a blasphemer and is in he'll boiling in a pool of excrement. That along with passages that state its permissible to steal a goys organ if a jew needs it, its permissible to rip off a goy for a jews own gain, its okay to usurp a goy but never a jew and hundreds more. The non jews, goyim, are merely cattle to serve the Jewish people and we should he happy to have such a purpose in life. Even mendel schneerson said that jews were the supreme race and the best goys can hope for is to lick a jews feet.....
How can you expect me or anyone else for that matter to be friendly to a Talmud abiding jew when we know what is written in their books? I may add there's one passage too in the Talmud that states ' jews should lie when asked what is in their scripture for if the goyim knew what was inside they would certainly kill us'
Id like to point out that the koran, which I've read front to back and has some violence but nonetheless doesn't have any of the extremely deceptive manipulative completely antisocial borderline psychopathic content of the Talmud.
If you think I'm wrong, pick up a copy of the Talmud especially the sanhedrin and soon you'll realise that the whole theme is 'us versus them' and how to win by whatever means necessary.
Sources: Talmud especially the sanhedrin, Torah, practicing orthodox girlfriend (former orthodox community member but still practicing jew - she left when her family tried to put her into an arranged marriage at 16). Also I've been to Israel as I worked for an Israeli company
Netenyahu can criticise Carter's book peace not apartheid but I can tell you from what I've seen with my own eyes - there is a very harsh state of apartheid and the Palestinians are treated literally like garbage - just to be left outside of a big wall and make life so terrible for them to travel (imagine going through some 10 checkpoints on a 30 45 min commute to work - itd drive you insane too after a while).
