I’m not asking people to stay in their lane, which is about disregarding their opinion based on their own circumstances. But I think its possible to argue an opinion without adding ad hominem attacks (e.g. well, you’re just an idiot ) or poisoning the well ( Anyone who disagrees with me is insincere about their convictions )
I assume you don’t mean to imply the internet population on average is incapaalble of discussing serious matters without popping off like the Midnight Bomber What Bombs At Midnight. Granted I have a background in tech support but that should not be a step up from the average regarding basic civility.
