I'll accept your non-apology, I guess. I don't get the joke. Jews are cheap? Ha-ha, that's a good one. Never heard that before.
The fact that you're Jewish – does that make it okay? I don't know.
Maybe I'm easily offended. But no, I don't like antisemitism or racism or homophobia or any of that shit. And yes, I'll call it out when I see it – even on the internet and especially this forum because I don't want to see it fucked up by a bunch of trolls. And before you start in about the "PC police" or "safe spaces" or any of that shit... It's called trying not to be asshole when you can avoid it. A good policy to live by I think.
