Off hand Jewish jokes / criticism even from people who otherwise seem pretty PC and ok. Just little digs or low key insults popped in to otherwise normal conversation now and again in a way they'd never do if it was about another race or religion.
I've noticed this for years. I'm 30 and my mother's side of the family are Jewish although many are now non religious.
In the last couple of months even my (not very observant) not Jewish DH has noticed and even later said to me 'did you think it was awkward that .... said that'
Anyway, just wanted to write it down somewhere as it's been on my mind a little.
