They also see the American right as “evil” Christians. Never mind that these Christians are their, and Israel’s, strongest defenders. Far more than the left.
Not only so, but back in the middle ages, it was Christians they saw as their worse enemy, not the Muslims, they thought them almost like themselves...who today would behead every one of them if they could.
Post #16 is the closest to the truth, unfortunately.
Back in the Middle Ages, Jews were treated much better in Moslem countries than in Christian ones. Some Jews just don't realize that it's not the Middle Ages anymore.
I think a lot of the older Jews have some bad memories about Christians forcing them to say Christian prayers in Public schools, and other humiliations along these lines. I've spoken with some who remember this and still resent the h3ll out of it.
Given that most families stick with whatever party their parents belonged to, it's not unusual that old animosities carry on into subsequent generations.
Multi-Generational bias for past wrongs.
There are other reasons as well. I used to ponder this question, and I had thought of several factors that might play a role.
