nobody is 'like that' in real life because there is way more context in real life.
on the interent a huge part of waht is interpreted is pure projection devoid of context. hence why people overreact to everything that they'd never react to if they heard irl.
it's funny. i used to be part of a forum where i was super controversial, then people would meet me irl, confront me about how evil i was... and then end up agreeing with me when i restated my opinions with a face and a voice and a tone.
most people were often interpreting me in such a way as to believe i was saying the opposite of what i was saying... as in they were projecting their fears and insecurities onto my words. they didn't do that as much face to face. after they met me face to face i went from being this 'evil cruel bastard' to the 'kind and generous' person.
i also notice that the insecure hateful people IRL, make stupid accusations about me projecting their behaviour onto me constantly.
