As much as I find Brianna Wu to be an irritating individual, I'll at least respect her pronouns because she has put in some effort to pass and live as a woman, poorly across the board it may be. She always struck me as one of the "old school" trans individuals who've opted to make their identities less of a circus-y attention whoring sideshow and more just a part of who they are but not the whole of who they are. I give Brianna that much.
Keffals, on the other hand, is flat out vile and doesn't deserve any pronoun respecting whatsoever; I'd argue Keffals has done way more harm to the trans cause than Brianna has.
