I'm not arguing for pristine threads. Im arguing for what @amerika calls decorum. everybody can express strong opinions even as replies, just don't be an asshole.
imagine you like having parties with contentious convos, but some guy is just rude. he doesn't get invited next time. now imagine you must pick your guests randomly from different neighborhoods and one neighborhood sends about 80% assholes but 20% interesting/dissident views. I'm asking they tighten that up.
