What I'm reading, in my 10-minute tea break (who am I kidding, I'll be at least half an hour) is someone who thinks that being transgender or being different means that you shouldn't be held to the same expectations of honesty and decency as the rest of the population. You're a trans woman who's joined an extreme right faction and then murdered someone — it's down to the fact that you were lonely and the only people who befriended you were murderous fascists. It's as if Whittle is arguing that transpeople aren't responsible adults like ordinary criminals.
Likewise the example of the TW who invented a drink problem in order to rise through the ranks of AA. Which suggests that SW thinks it's perfectly fine for transpeople to dupe people for their own purposes. As I, in the lesbian community, can attest happens all the time. It really is a case of, if it'll make you feel better about yourself, transpeople, do it and don't worry about the ethics or the damage you cause because none of the social rules apply to you.
