I'm an antinatalist too, and although I don't identify as one, I have traits of misanthropy.
There's a saying in my language "A human is a wolf to a human" which pretty much means humans are people's biggest enemies. I really wish I could live in a world with my own sense of justice and morality.
I hate when I see bad people do bad things, but the society says "It's not illegal, but it's illegal for you to try and fix the issue". And I hate when I see someone do something good, and society again is pulling laws and rules out of its ass to justify criminalizing good deeds.
I like a person, but I hate people. There's another saying in my language "The more the cooks, the worse the soup". Humans can be intelligent and good when alone and turn into mindless monsters when around other people.
