Now it should be easier for non-Jews to understand. A high percentage of the U.S. Jewish community only sees its Jewishness in the sense of its leftism. This is particularly true among younger Reform Jews - so much so that an Orthodox rabbi said in a Jewish magazine recently that many people gravitate to Reform temples only because they are the "address" (his word) for their politics, not for the religious tenets that Reform Judaism supposedly is.
As a member of a Reform temple, I find the issues you raise here fairly compelling, not to say disturbing. I have had some discussion with my rabbi (who is a leftist but a nice guy) on this subject, but usually find that not so many people really want to talk about it. Do you mind if I freepmail you on it?
