Some of what you say has a bit of truth to it, such as not being able to join certain clubs, tho I would never want to join one which didn’t want me.
Some of the other stuff such as not celebrating Jewish holidays is nonsense. I am sure Israel does not celebrate Christian ones.
There is also another side. I used to work with a U.S. Treasury agent. He was a fine man and extremely intelligent. He once told me the best neighbor he ever had was in Atlanta and the guy was Jewish.
He got a promotion and moved to New York. He bought a house in a neighborhood which was mostly Jewish. He said they were the rudest people in the world. Also made it plain they did not care for him because he was Christian.
In other words they mistreated non Jews much worse than Christians do non Christians.
Remember also that while many Christians have been in the US for generations, many Jews have only been here for a generation or two.
I grew up in a household with both my mother and grandfather. We both learned of his early life from a very young age. While I wouldn't say he hated Christians, he certainly distrusted them (he made no distinction, but I believe that his anger would have been directed at Catholics and Russian Orthodox). He grew up in Western Poland, living through a number of pograms in his village. He managed to escape to Russia, making boots for the Czar's army, and learned to hate the Russians in general.
When you wonder why it seems that so many Jews don't like or trust Christians, remember that many of the wounds haven't had much time to heal.
