“Can everyone now say outloud that OO founder and leader Avi Weiss is not frum?”
To say that would be motzi shem ra. Even his most bitter opponents had to admit that he is a kosher eid.
Excerpts from an article by R’ Mordechai Willig titled Trampled Laws (http://www.torahweb.org/torah/2015/parsha/rwil_ekev.html):
“Rav Moshe continued to say that no battle, even one supported by the entire world, can succeed in changing the Torah, and women who fight to change the Torah’s eternal and immutable laws are heretics. If a woman wears talis or tefillin as a complaint against Hashem and His Torah it is prohibited as heresy since she thinks that it is possible to change Torah law… The movement to which Rav Moshe refers, now known as feminism or egalitarianism, continues to infiltrate Orthodox Judaism. The recent ordination of women is but one example. Unfortunately this practice is viewed by at least one of its proponents as part of an attempt to change Torah laws and ideas (see Crosscurrents July 29, 2015), precisely the heresy that Rav Moshe warned against.”
For a more in-depth look at apikorsos in Open-Orthodox theology, I suggest reading an excellent article titled “Open Orthodoxy: Outright Heresy and the Orthodox Rebirth of the Conservative Movement” by Rabbi Avrohom Gordimer.
