It depends. If you sit and talk with some of them and listen carefully, a lot of times it starts with "It's really just about Israel", but there's a lot of "hidden" Anti-Semitism under the surface with a lot of Liberal types. Don't forget, the banks are "evil" and keeping everybody poor, and "The Jews run the banks", so... connect the dots. Also, sounds kinda familiar, don't it?
Truthfully, a lot of Liberals are just as prejudiced as anyone else, they either just hide it better because they know it's not "polite", or, they disguise it as "helping", like affirmative action. Affirmative action is racist because it implicitly suggests that minorities can't succeed without Special Help being given to them, but liberals argue that it's merely a course-correction in response to the Evil White Male Agenda holding everybody down. But the truth is, it's just racism with a pretty skirt on. "It's not your fault you're not good enough" is still saying "You're not good enough." Which is racist.

Being raised Catholic, and with my awesome Irish blood being diluted with some Polish pisswater, the far-Right have no love for my mongrel ass any more than they do for the Jews.

And yet, I'm a white, straight male, so I'm currently not a friend to the far-Left, either, simply by existing. Tough to find an ally on either pole, these days. The safest bet, as always, is somewhere far away from extremes and somewhere in the middle.
