Maybe the better thing to concentrate on is why you felt like that comment was necessary. You didn’t seem to have a goal behind it, other than drawing more attention. It’s really not relevant to the discussion or the post. So why post it? It felt like your intention was just to talk shit about a random person, and maybe you should think about that.
I think this is true, but I also grew up without Internet or social media so maybe things were more regional as opposed to this larger shared culture those things have enabled. So that may be part of it?
