Yes. Takes nothing out of my day to help educate some people.
BUT - I was never the type to waste my time either. If I see someone's not getting it or I see someone is simply making a mistake, I'm really not gonna waste my energy. That person is either being willfully ignorant (in which case I can't help them) or they just had a slip (and everyone makes mistakes, it's just mean-spirited to browbeat someone for making mistakes).
I've never actually been accused of being a SJW, at least not to my face.
