Get over it! Just because I live in Israel people assume I am Jewish (although I think religeon is stupid so I don't take part in it), anyway I see plenty of 'stupid jew' shouts on the internet or 'joob', sure it's silly, but if you as me it's even more silly to make a big deal about it, since you can't help it. So who cares!
Let me sum it up for you, you have this problem with the 'racism on jj2', this problem hasn't got a sollution, you can't help it, (so that means also crying won't help). So the only option is to get along with it, and carry on in normal life (in other words who cares heh).
