The fact of the matter is that many Jews tend to me liberal and support liberal chi chi causes like the environment. There are also observant Jews who are in favor of Israel giving up land to the Arabs, and who love Yitzchak Rabin, Shimon Peres, etc. My brother in law is an example of that. When I asked Chaim about it on a past Ask JTF show, he didn't know what to say.
Likewise, there are many left leaning Christians in America, and they make up even more of America's population. So rather than criticizing religions (except for Islam, which is fair game here), we should instead focus on *people* who act hypocritically, despite professing to be religious.
