some migrants and their siblings are no longer happy living in multi cultural society
The "multi-kulti" is a key word here. Notice the cheating which is hidden behind this word. First, immigrants were brought down to Europe to do work the "Caucasian race" didn't want to do. Then, their families came and in the end the multi-culti ideology was conceived by the European libtards to wrap it all up nicely for the political marketing purposes. Those libtards preferred reading books over cleaning the toilets (the famous case of the British libtards attributing toilet cleaning onto Wulkan, a Polish
immigré to the UK, comes to mind here). The multi-kulti idea was created simply to justify the blunt economic reasons behind the so-called multi-cultural society.
Poor Angela Merkel naively believed that the multi-culti was a genuine idea and invited refugees of war to come
en masse to Europe. In reality, it is impossible to assimilate large groups of foreing people in a relatively short period of time. It takes centuries, not tens of years, and the result will still be uncertain. So multi-cultural societies did never exist in post-war Europe in the result of the inflow of immigrating people. Just as the Soviet idea of
homo sovieticus had failed some time ago, the Western European idea of
homo multiculturalis is failing right now.
An 18-year-old German-Iranian gunman
I wouldn't call him 'German' since he has been in Germany for only two years. Will a two-year stay in Germany make a German of you? I doubt it, so let's call him 'Iranian' even if he had his German identity card.
Because, Ziemowit, Poland is becoming ever more vulnerable to Syrian migrants, uncritically allowed into the country,
I sense a lot of irony in that sentence of yours, Łyżko ...
