On avgerage are Eastern European men more violent or is it just a stereotype?

Personally I have a hard time believing it is not a stereotype, I have lived in a neighborhood with lots of Eastern European immigrants long enough and seen how sometimes young Russian men and Ukrainian men behave: they actually try to pick up fights with random people for no reason sometimes. Also, Polish men are violent, one thing I know is that you should never pick up a fight with Russian man or Ukrainian man or Polish man. My experience is anecdotal though.
