I had a couple paragraphs of what amounted to trauma-dumping that I'll spare you, but it's my inclination to believe that it's not always misanthropy but just alienation from a hollow, cruel, and ugly collection of circumscribed commercial transactions and loneliness calling itself a society, leading to people just wanting space because they aren't taught how to cope except by being an atom in the void. I understand this less with people who have friends, though.
