As a person of Jewish identity, I am highly offended not by Glenn Beck's statement of unpleasant facts but by the actions of individuals (like Eric Yoffie) who, by purveying left-wing politics under color of Judaism
I think you are missing the point on Beck.
BOTH Eric Yoffie and Glenn Beck equated ALL of Reform Judaism as just a vehicle to purvey left-wing politics.
Try this Catholic thread. Glenn Beck isn't doing too well on it.
Two wrongs do not make a right but, as Yoffie did what he did under color of Reform Judaism, I can see where Beck is coming from. You are correct, however, that Beck should have separated the action of Reform “leaders” like Yoffie from Reform Jews as a whole, which is what I do emphatically every time I write on this subject.
