Why do you only see Jews driving cars? They're still too scared to take the train
Why do you think that, is there some kind of reason for it?
No. Fuck the jews and their holocaust.
I'm not sure why there needed to be something so harsh said about Jewish people. I think that learning more about what they went through would change your opinion about Jewish people. In the meantime, try to avoid jokes about the Holocaust as it is a very sad and traumatizing time in Jewish history.
