@apos Yeah, I see what you mean.
I think the stances in that particular debate are "words are just words" and "slurs are words that, when used, in any context, cause harm."
But I can agree 100% with your point that political leanings don't have much to do with what we're discussing so much as whether moderation for those words needs to be active or simply left as-is (ie. there is a rule about no homophobia/racism/discrimination, etc. in the rules of the forum) and we leave the things that fall beyond the scope (such as the usage of some words people find unpleasant) as "legal gray area", in the way that I see it.
I think, preferably, we might want to not open the political can of worms.
(PS: while holocaust denial is protected speech in the US, you get jail-time in about 90% of the other countries that are signatory to a certain UN Convention on Human Rights. On the other hand, I am a long time admirer of the almost-absolute sanctity of freedom of speech in your country. It defeats the point of the real crazies out there when they're allowed to say their things and can be dismissed out of hand, versus censoring them and then they have that as confirmation bias to point out to others that might be susceptible to the siren's call of political violence.)
