Myself, I’ve never understood anti-Semitism
There’s nothing in the Bible that changes their status from God’s Chosen People to something else.
If the anti-Semitism stems from the Crucifixion, it seems to me that the Romans (modern Italians) are equally culpable. But anti-Italianism is almost non-existant.
Sure, a large majority of American Jews are liberals or democrats, but that is individual behavior. I know several conservative Jews that make up for some of the liberalism of most Jews.
The disciples were despised by the Jewish leaders, and the feeling was mutual. The strongest feuds usually being between relatives, the Jews and the Christian Jews bore animosity towards each other that carried over through the ages.
In addition, although European Jews were barred from trade guilds, educated Jews prospered in business and finance, prompting envy among poor gentiles.
And then there is the fact that people are idiots.
