I can understand that. Much of the world conspires to finish what Hitler nearly accomplished. Every Christian and every Jew should be on guard against that evil. It's all around us.
Plus when guys say "shit" they don't have to literally mean "shit". It can mean nonsense or stuff
Having had a father whose every other word was just as you write, I understand your point. I just think if the comment went the other way Jews would likewise take offense. I think that just comes with being in the minority.
There must be some Jewish tribalism otherwise Jews would have ceased to exist long ago. Plus with only 14 million Jews in the world .....so I think (logically) you act a bit defensive. The big Jewish mistake is being defensive about Christianity when it must be Islam. The Israeli Jews know this better than the hot house flower Jews of America.
This country is so big and wealthy that you can stake out any absurd position and you will find thousands or millions that agree with you. So here you will find the leftist Jews saying the worst things about Israel. I would like to fly them over the West Bank and kick them out of the helicopter
