TL;DR of the above for anyone else: Socializing is a muscle which can and should be exercised.
Which I actually wholeheartedly agree with. I had a similar experience to you, though not as extreme. I had maybe one friend, didn't talk to people, considered myself an introvert, basically the typical person you're talking about. Then I met someone who taught me how to exercise that muscle, and encouraged me to meet other people. Took some time, but I went from having one friend, to having over a dozen. And I'm capable of actually talking to people I don't know now, instead of clamming up and getting anxious, most of the time. Barring certain physical or mental disabilities, I always try to encourage my introvert friends to talk to others more, as much as it's a horribly embarrassing, awkward, and especially draining experience at first.
This all being said, you sound like a douche. Especially with that last paragraph. Chill, my dude. Don't immediately assume you're gonna be under attack. There's hardly enough people on this site to spam you with replies anyways.
I'm actually interested, how would that work? As far as I know, anarchism is based around the removal of a state, so would it be up to the people to enforce these regulations? Or are we sorta working on the honour system here?
