The GP established there are legitimate conversations being had about aspects of the Holocaust that do not deny that it happened. This is a nuance that sets a precedent for other discussions of controversial topics. I think it’s important that common people understand the difference between Denial, Revisionism, and legitimate debate, and have a way of discovering this information without being lumped in with antisemites

I somewhat agree that it doesn’t “need” to happen on Facebook, and I think it’s OK to stake that out as a rule: Don’t debate anything about the Holocaust on Facebook, take it elsewhere. Meet with your history buff friends on Telegram and hash it out.
