No, the distinction here is between SJWs and TUMBLR SJWs. One can serve a valid social purpose, the other uses racism and misogyny and gender politics etc as brickbats to beat down anyone who's got a ship or opinion they don't like, regardless of how applicable the term is to said ship or opinion. It's a cross between crying 'wolf' and shouting 'fire' in a crowded theater. It can hurt people and make people more likely to brush off genuine issues as 'just another Tumblrite'.
