Have you heard the one about why Jew's don't eat pussy? It's because it's so close to the gas chamber.
Do you find that funny? I'm really surprised you'd make a joke like that.
It's just a silly fun joke. My parents used to say it when I was a kid and now I say it whenever I'm in an argument with a liberal.
Jokes are fine and it being one you heard form your parents of course you would think it's okay to say. But the Holocaust was a time in Jewish history where an entire group of people were litterally afraid for their lives every day. I think you should learn more about the topic to get a better understanding so you can have some more perspective on why a joke like that can be so harmful.
Yea, yea, I know your liberal history. I just love making fun of Jews.
Would you like to come to a museum with me and learn more about it, though? If you still find this sort of joke funny then maybe you've not looked as much into as you think, because it was a real tragedy.
