I can believe it, though I believe it to be untrue. SJW is not a neutral term. In the same way that the word "woke" has been corrupted, SJW now almost exclusively refers to dyed-hair screaming women making mountains out of molehills to try to strongarm people into policing things they don't like. It did not used to mean that, but it is now used primarily pejoratively, not descriptively, like "woke".
