Theory: Devorah Feldman = Bar Kamtza
Rejected for bad reasons, and therefore telling half-truths to put Satmer in a bad light. It worked, and whom does the Gemorah blame for Bar Kamtza? Use this as a springboard to fix the issues that are discussed, instead of trying to stuff them under the carpet together withe everything else.
MS: He brings in too many Holocaust comparisons to be credible. Your author is using scare tactics, which makes me wonder what the real reason is why he is scared.
Personally, as I have said before, you/we should not care what other people think. Avraham HaIvri was against the entire world, but he was right and followed Hashem. That is what counts, not trying to get the world to “like” you.
