Hve any insufferable SJWs in your life? That's social justice warrior, per Roosh V:
Social justice warriors believe in an extreme left-wing ideology that combines feminism, progressivism, and political correctness into a totalitarian system that attempts to censor speech and promote fringe lifestyles while actively discriminating against men, particularly white men. They are the internet activist arm of Western progressivism that acts as a vigilante group to ensure compliance and homogeny of far left thought.
They're the PC thug faction of the progressive left, in other words. Here is one of the most delightful takedowns of them ever:
They’re clearly the sort of penny-ante fascists who congregate in the elective posts in community theatre, school boards, and homeowners’ associations, who like being able to lord it over a bunch of other people but don’t have the balls to actually run for something important.
What makes the piece intersting to me is that it's in the context of science fiction, one of my favorite genres. It handily dismisses the notion that once upon a time there weren'rt enough female SF writers and the novels weren't feminist enough. It's by Charlie Martin, whom I haven't read, at the blog of Sarah Hoyt, whom I have. I recommend "Wings," a collection of her short stories.
