Yell? Why are you talking about yelling when there was no mention of it. You were supposed to imagine the "lol you suck" comment as something with the intonation of "oops I dropped my pen". With no change in emotion, regular neutrality just pointing out the fact that someone suck.

I explained this very clearly as well. You just incorrectly believe the "victim" has no blame of their own, which of course is objectively wrong in the vast majority of "toxicity" cases.
