People really like to gloss over how deeply rooted Jew hatred is in Islam. The Koran contains blatant hate speech against Jews and this is the primary reason why Muslims resent the existence of Israel so irrationally
Because it isn't symmetric at all. Mohamed added all the of hate speech about Jews because they sensibly didn't believe he was a prophet. It is remarkably similar to how L Ron Hubbard taught his followers to hate Psychologists because they rightly called him out for his bullshit.
