Sure, we have a racism problem in Eastern Germany. But I don't think a far right activist might jump out of the next bush in many cases. Leipzig should be the best of all these places.
And to be fair, that kind of daily racism is a problem all over the country.
I live on the other side of the border and from the outside it seems like an economically-left-behind-after-communism kind of problem.
We have the same issue and these people gravitate towards nationalist circles because it gives them a sense of belonging in a world that largely doesn't care about them.
Doesn't make them activists of any kind though - just hooligans looking for meaning.
