Why is misanthropy not considered bigotry?

[devonin]

I don't think anybody in the history of facebook that has posted "I hate all humans" is actually a misanthrope. They've had a bad interaction with someone and are being hyperbolic for attention.

Actual misanthropes don't have facebook because why would you want to interact with people if you can't stand people?

In fact, expressing misanthropic ideas to get attention or approval from other people is directly contradictory to what misanthropy is.
