I do not know why there's still quite a bit of Nazism going on in Germany, but I've seen such demonstrations in a city. I guess that not all Germans like having their country shared with foreigners and think of themselves as a stronger nation, better off without any foreign individual. It is true that the majority of immigrants in Germany are the Turks and (the majority) due to their lack of education end up living off social welfare that the German taxpayer has to fund. This might further fuel Nazism.

As for Russia, the gangs that have been mentioned are mostly made of immigrants into Russia. The countries where they originate from is Kazakhstan, Armenia, Tajikistan and Uzbekistan. These immigrants are known to be the more violent and are moving to large Russian cities to try and make a better living. This is the information I have been told.
