Is there a specific word that indicates people who hate others?

Perhaps a casual term for someone who hates others is a "hater" or "haters," especially in reference to famous people. A more formal word is "misanthrope," but this is hardly ever used! Ex: Taylor Swift's haters hate when she has a good time. Ex: Don't be such a hater. Ex: He was a misanthrope.
