Sure, and that's my point: Are you just venting? Fine. You're making a choice to vent your frustrations and not hoping to actually have a discussion. You're making yourself feel better. There's nothing wrong with that, either. We all vent in different ways.
It's just unfortunate that many people choose to make internet comments the location of their venting. Worse, this becomes the sort of discourse that we come to expect from any sort of public internet forum. We don't expect reasonable discussion: We expect angry people yelling about the other team and how their team is the best team. It's become a stadium full of drunk fans.
> It would be more diplomatic, sure.
Eh, not really: I never mentioned left/right in that chunk of text on purpose (because I think both "teams" do it). So your rewrite is actually significantly less diplomatic because it singles out one group of people who previously were part of a larger group.
Might seem annoying of me to call you out on this (and I fully understand why you assumed that given the context of our discussion), but I think it's an important correction nonetheless.
