The term "SJW" is like "liberal" and "feminist."
There is a disconnect between the true meaning of the words and what they've come to mean in modern society. It's Orwellian, actually.
Describing somebody as a liberal used to mean that they supported individual rights and freedoms over an authoritarian state. Nowadays a "liberal" would describe the exact opposite.
Once upon a time, feminists fought to achieve the same rights as men (equality). Nowadays, the majority of women who call themselves feminists fight for mass Islamic migration, when Islam believes in female genital mutilation, beating wives if they disobey, raping women who don't cover up properly... etc. Modern feminism has become more about destroying Western men than about equality, which is why most Western women, to their credit, don't identify as feminists anymore in polls, even though they believe in equality.
Social justice warriors, like MLK, used to believe in equal rights and opportunity for all. Nowadays, SJWs preach "white privilege" and believe in affirmative action when it comes to university admission and the hiring process. *Note it would be one thing if affirmative action were based on a person's income level (though I personally still wouldn't agree with it) but basing it on a person's skin color or sexual orientation is the very definition of racism/discrimination. SJWs also judge peoples' opinions not based on the merit of their argument but based on whether or not they are a member of a victim class. For example, there are many videos on youtube where an individual brings up a valid point and the SJW retorts with: "You're a white male." .... or in AIDS Skrillex's case: "You're f*cking a white male."
Modern day SJWs are not about justice or equality.
