I would think anti-Christian sentiments among Jews is confined to the Orthodox, especially the ultra-Orthodox. Ironically, this is the one segment of the Jewish population that votes for Republicans. Hasidic Jews in Rockland County, NY, a suburban county in the New York City area, have helped to flip the county from blue to red in 2024. Hasidic Jewish districts in Brooklyn massively rejected Mandami for mayor, even more so than the remaining white, mostly Catholic enclaves in Staten Island and southern Brooklyn.

Not in my experience. Leftist Jews, Reform Jews (but I repeat myself) Conservative Jews and of course the Orthodox all dislike Christians.
Such a high rate of intermarriage suggests that many non-Orthodox, particularly Reform, Jews lack animosity towards Gentiles.
