A liberal extremist. The kind who is so liberal that they're delusional. They're generally angry feminazis, neckbeards from Tumblr or YouTube, or whiny teenagers. They're the ones burning American flags, shitting on Christians on the internet and protesting over the tiniest things. They're the whining feminists who think criticism should be illegal. They're the people who vote for Hilary JUST because she's a women. You can commonly find them online, in liberal campus clubs, and protesting at churches.
