gnaw. trolls happen. i don't like that they do. but they're just part of diversity including everything. one very small part. in real life, they can create death camps and ship people who aren't good enough at lying to themselves off to them. we know this, because it has happened in real life. and enlightened ages can revert to ages of feudalism. but there remains considerable difference between angry words on a screen, and the physical destructiveness of an angry mob.
I would say I'm extroverted although not entirely so if that makes any sense. I like my own space and have a sensitive personality, so when I'm among a group of people or friends for instance, I don't join in with their gang mentality. I much prefer to speak to a smaller group of people than a large noisier one with strong personalities. I'm certainly not introverted by any means, I like being in the company of people, and I'm not afraid of communicating with anyone really.
