For certain viewpoints that are fundamental ly hard to challenge, a reasonable middle ground to me is to just talk about something else and respect other peoples viewpoints. This is usually how religion is (or should be) treated in open public spaces. But it's by no means easy and I can't really blame vegetarians for being passionate about it either. But I see this more from the perspective of how to behave around other people and not so much what I personally believe, but maybe that's largely cultural. (Norwegian)
For example, I have strong opinions about people believing in things without sufficient evidence, but unless I'm in the correct space or is invited to, I'd rather keep it to myself.
Yes I'm with you culturally speaking (British). I suppose the difference I see here is this is a forum for the exchange of ideas, not a social space where there are other, more important factors at play e.g. the maintenance of friendships, of having a pleasant evening etc. I think as with everything there has to be some judgment, but if someone brings up Grok, for example, I don't think Elon's politics are _irrelevant_ to the discussion, unless the discussion is literally "Let us all now turn to the question of memory architecture" or what have you. But if it's just sharing a link, then to me the implied discussion space is quite broad.
