Rabbi Without A Cause, the RCA-affiliated rabbi so loved by Rabbi Gil Student (and so ridiculed by many of Gil’s readers and by me) has this to say about the behavior of the ‘gedolim’ in the Rabbi Slifkin Ban:
[L]abelling books kefirah and someone a kofer is well-within halachah, as is refusing to meet,if the claims are well-grounded. Read the position of Rabbi Akiva in Perek Chelek.
In other words, a shomer Shabbat Jew with recognized smicha wrote a series of books that quoted Rishonim and later authorities. Gedolim labeled those positions heresy, and Rabbi Slifkin a heretic. They refused to meet with him or his representatives. And, when pushed by others to explain themselves, they were left with saying that what was permissible for Maimonides or Nachmanides or Rabbi Samson Rafael Hirsch to believe is not permissible for us.
These rabbinic fools tried to destroy Rabbi Slifkin. They did so with no due process granted to the man they condemned. And who defends their misbehavior? An RCA rabbi.
This is Orthodox Judaism. People, run away from it as fast as you can.
