Hating Jews?
I'd say a mixture of the following reasons:
-Jewish culture is very competetive, so that they perform well. They are generally rich and successful, although the difference in wealth is enormous.
-Jews prefer Jews. If youre a Jew, you usually prefer it if your kid marries a jew and when you have to hire someone out of two identical people, you choose the Jew (this stops very quickly if there is a difference in ability though, prob all cultures do this)
-People are probably often jealous of all the rich jews (was the reason for anti-semitism for Hitler)
-People don't like having consessions for stuff someone else did 60 years ago. The only reason for all the conflict in the middle east is that we felt guilty and had to give the jews land in return. It is brought up any time they get an advantage from it, people don't like that.
-Israel vs Palastine, Jews came later and Jews are way stronger and get all the foreign aid (billions of USD, while Africa starves), and people usually like the underdog (not like the Palastinians have a serious chance with brute force against them), They are allowed to have nukes while Iran doesn't, etc
-We used to, and its a little stuck in our civilization, jokes about jews, etc
-Jews believe they are better than everyone else, they are the god protected people, they should have Israel, they were picked out, they ... Other people dont like that
-For the hard-core Christians, they killed Christ
