Not to justify anti-Semitism, but why is there always talk about it but never any mention of anti-Christian sentiment among the Jews?
I think that's a very fair question. It might have to do with the power differentials, the Jews never being a large nation or having an empire were rarely in as good a position to weaponize their anti-Christianity as (some) Christian (and Islamic, and Pagan) nations were to weaponize their anti-Jewish beliefs and feelings.
And of course this culminated in the Holocaust, which while there were many other victims of the Nazi terror, was obsessively focused on the Jews.
Anyway, that's my first draft answer of "why the focus on anti-Semtism and not anti-Christianity. As it relates to the news in the USA today, it's not Christian students who are being threatened in all of these campus encampments, it's Jews (ethnically and religiously) who are. So, that's why anti-Semitism is topical right now, and perhaps anti-Christianity isn't so much.
Historically the biggest and most effective anti-Christian ideology has been Islam, by far, and not Judaism, I would argue.
None the less I find your question so interesting that I will devote some future posts to the question of Jewish anti-Christianity or anti-European (white people) prejudice.
Thanks for the interesting comment.
Yet anti-Christianity existed before anti-Judaism. (There are Semites who are not Jews).
The Apostles celebrated Passover behind locked doors for fear of the Jews. While Christ was killed at the Crucifixion on Good Friday, on Pentecost (meaning "fiftieth day") after Christ's death, the Apostles received the Holy Spirit and His gift of speaking in tongues enabled them to spread The Word, the beginning of the spread of Christianity to the people.
Jews don’t have much of a record of mass slaughtering Christians, so it’s a less important topic.
