there was a great study a few years that went into the whole "ppl online are bigger jerks than irl cuz theres a virtual wall and no repercussions" and the researchers were expecting to see that be the case but it turns out that people who were really angry or argumentative online were also found to just be assholes in person and people who were pretty patient and nice online were found to be patient and nice in real person as well
and it just debunked that whole cynical idea that people will naturally be mean if theres no punishment for it
the researchers found that being online didnt make people more hostile, but that being online allowed already hostile people to dominate forum conversations, and the less aggressive people were much less likely to reply or engage, ending in just the aggressive people bickering at eachother
