"Don't waste my time with your hate or anger (and maybe try to stop wasting your own time too?)"

Disagreeing is to be expected and even welcomed in any discussion. I also don't mind people not sharing my views, and I don't even mind people not 'liking' me (why should I? We're not living together). I do mind ad hominem attacks, insults and bad faith arguments, because those are not a discussion anymore: the idea is not to exchange contradictory arguments anymore but to somehow hurt the other person, or to hurt their reputation in the eyes of other users. The moment I realize what's going on, I will block the person doing that. (edit: I will not try to discuss any further, nor try to explain other participants what I just realized, I will simply say "thx, have a nice day", or something like that, and block them once and for all)

They are free to keep on throwing insults (and non-sense) around if that's what they want their online presence to be... exactly like I'm free, literally freed from wasting a second more of my own time reading them. That's not worth it.
