I read somewhere that begging can be stopped if they...look normal and unable to beg.
In more conservative places this would definitely work as a deterrent but in irredeemably lefttard strongholds it simply won't.
London (yes, the UK one) has a lot of beggars and excrement caked streets too (canine or human is anyone's guess).
Each and every time I was there I was accosted by beggars.
Here are two stand out examples:
One happened inside their "Tube" metro system. I was approached by this guy in his 20s or 30s who had cut and fluorescent colored hair, a heavy leather jacket, and more metal piercings in his face than I've seen in a jeweler's display case. He actually grunted in disbelief when I declined his request for money.
Another time some short, pudgy, middle aged woman with long, greasy hair came up to me on the street and asked for money. I told her I might have some change to which she immediately and angrily replied "Don't you have any notes?!" I firmly told her no and she stormed off.
So yes the British are actually as bad in real life as they are on here. They're all poor too.
