The problem I've found in having these conversations is that, for some people, the moment you disagree with their "simple, basic, realistic human values", things turn toxic. Ie. it's not really a discussion, it's "these are my values and you either agree with them or you're a terrible person".

For example, I saw a comment thread on this board about Black Lives Matter. It had devolved to the point where one commenter said something like, "BLM means that you either believe that black lives literally matter or you do not.", which, obviously, is not true.
