Did you know Jewish rabbis aren't allowed to accept payment for circumcisions ? They just keep the tips!
That's a disturbing visual!
Ah yes, because they know they'll have problems if they charge what other people do. And because they are gay .
It sounds like you have a lot of views of Jewish culture that may not be accurate. I think the best thing to do is find someone who is knowledgeable about the topic and ask questions. That way, if you do want to make jokes, they'll be more fitting.
