What is is this nonsense about hating humans?

I call it 'internalized antisociability.' Where people who're socially ostracized (for any number of reasons) internalize that disconnection and decide to just casually disdain other people rather than build social skills. Usually also comes with an undeserved superiority complex.

I am not sure I understand what you mean by "Hating humans" do you mean people who say "humans are an evil spieces" or people who say "I hate people"? For example, I love humans and humanity as a species but I am not big fan of being around people socially.

I used to be misanthropic... Like in middle school. But I'm past it now, and generally find people who claim to hate humans, or reality itself, a bore these days. Its just kind of an uncreative world view adapted ironically by a lot of creative types of people who just don't want to even try. And I get it. A lot of people who say they hate humans don't actually HATE humans. But back in middle school, when I said that a lot, I was just trying to give myself a justification for not actually talking to people. And man, I wish I coulda spent that time more productively now.

Humans > reptillians I'm not saying it's aliens but it's aliens.

It isn't nonsense... try living as a nationalist for your entire childhood, only to realize that your country is horrible when going through 8th grade US History, and then slowly watching your country devolve into a capitalist cesspool. While not the entire human race is horrible, there is enough of them to start the hatred. In my case, the hatred is literal and is very rational.
