I wouldn't exactly put it that "most Jews are pro abortion." I would say more that the group you speak of is fervently opposed to the government having anything to say about anything to do with sex, which is what they think a pregnancy relates to. I and many other Jews disagree on this, by the way. But I am trying to make a distinction between being pro-abortion as, say, the Red Chinese are, and a group who is (wrongly) libertarian on social issues. This is rather amusing. If there is one thing Judaism is against, it is sexual libertinism. We regulate sex within marriage. (Laws of Sexual purity). That liberal American Jews support licence, indicates to me that they are not representing Judaism at all, but leftists.
I agree with you on the religious points. Though I think, to be fair, a lot of my friends are liberal Jews and they make extremely moral choices in their own lives. They do live their values (life is too short to have friends who are hypocrites). They just can't bring themselves to "impose" their morals on others. Except, of course, when it comes to taxes!!!! Personally, they are very generous to truly needy causes (they are NOT political donors but rather volunteer at shelters, participate in literacy programs, support Habitat for Humanity, drug rehab programs, etc. -- in fact, we have some very dear friends where the husband has done well and the wife's family are all really struggling, so her husband is helping send her nieces and nephews to college and is helping her mother, whose alcoholic ex-husband impoverished her). But they have this view that, somehow, "the rich" are not doing their part, though it has been shown that, particularly religious people, are extremely generous in their personal lives, and not only to their churches but to other deserving causes as well. I try to give them the stats (Investors Business Daily is a FANTASTIC resource for this, btw, if anyone is interested), but their ideologies are just too ingrained to get through. Still, I'll keep trying.
When I think of the kinds of people you are talking about, the Barbra Streisands of the world come to mind. They want yours and my taxes to fund abortions in China, but they would never think of using their own ample funds to support their ideologies. As I said, though my friends disagree with me, they are nothing like that. They live their values. Although I disagree with them, I do respect the way they behave.
