One thing I find interesting about this is how the term Social Justice Warrior has totally evolved, and actually has become a legitimate symbol to be worn with pride.
I remember when the term first popped up, it mockingly referred to a very specific group of people---teenagers, usually white and privileged, on the Internet---who practiced a form of social justice that was more or less slacktivism. The "warrior" part was quite tongue-in-cheek.
Even worse, I remember the initial group of people associated with "SJW" were often mocked for doing the exact opposite, and delegitimizing the purpose of social justice by turning it into, as I've seen it called, "an oppression olympics". Particularly, the people who missed the actual point of trigger warning by making trigger warning for literally everything, no matter how benign, the people who basically mocked the idea of being trans by claiming to be "transracial", "transhandicapped", etc. And of course, the fictives, which turned mental illness into a cool lifestyle.
I mean, until this whole GamerGate thing started, I never considered people like Anita, or any gaming journalist, to be a "SJW"...that was a term reserved for people who were legitimately awful and turned the whole idea of "social justice" into a popularity contest and never sought to teach people. Now I see it being used around here, and I'll be honest, it's a bit hard to see that being used and I can never tell if people are using it in a positive sense, or a mocking sense.
