Social justice warrior
Social justice warrior (SJW) is a pejorative term and Internet meme mostly used for an individual who promotes socially progressive, left-wing or liberal views, including environmentalism, affirmative action, gun control, single payer healthcare, progressive taxation, feminism, abortion, LGBTQ rights, and multiculturalism. The accusation that somebody is an SJW carries implications that they are pursuing personal validation rather than any deep-seated conviction, and engaging in disingenuous arguments.
