Maybe they haven't but they have accepted the false gds of feminism, homosexuality, black liberation, and often times Arab anti-Semitism.
As you will expect from me, I will not quickly paint them all with such a brush. In my first post I explained that I have had experience, and I bet a lot of members here, have family members who would consider themselves reform jews. I don't condone it, but I cannot fully condemn it. I will attempt to lovingly rebuke those Jews who have gone off the path. Some may have issues which need to be worked out before they can become more observant. It is like many Rabbis explain that some religious Jews lost their faith after the Holocaust. We cannot be their judges because we did not live through that experience.
We have the mitzvah of loving the Jewish nation. This is called Ahavat Yisroel, and the opposite which is sinat Chinam or baseless hatred. A religious Jew should not feel that he is superior to the non-religious Jew. We, the religious, should attempt to reach out and bring them back into the right path. While I agree those who are wantonly rebellious will be dealt with Hashems righteous justice. But unless we know that they are helping the enemy {like NK and Pieces Now} we should give them the benefit of the doubt.
To judge all of reform judaism for the deeds of the few is not fair. It would be like judging all Orthodox Jews because of the deeds of those Rabbis in New Jersey or Jack Abramoff {
