I remember I got into an argument on reddit awhile ago with a person over Italian food. It got to the point they were following me into other subs to harass me. I clicked on their profile to block them and their most recent post was them drinking their own piss on r/piss. At that moment I realized I had spent so much pointless time arguing about the taste of food with someone who drinks their own piss as a hobby. This site is a shit hole.
Insults and comebacks are arguments. If I say you’re a fucking moron because you don’t understand basic argumentation and debate that is an argument. Choosing to dismiss an argument because the party delivering the argument is naked is a logical fallacy - there is no standard for argument.
