Oh man, I'm aware of a thread where this exact same thing was said by a transbian claiming to have a "lesbian" girlfriend. It was premised on the idea that homosexuality doesn't actually exist because some trans people can be literally "indistinguishable" from their target sex. He said that, therefore, it's not possible for someone to be exclusively same-sex attracted, and that that's bigotry. He clarified that "gender identity," on the other hand, was not questionable and that it's wrong to question someone's stated gender identity. He gave all of these answers but refused to answer the final question asked over and over to him because he knew what a piece of shit it made him look like, and just kept repeating that he already answered it, but also wouldn't clarify or point to where he answered it. Anyway, that question was (paraphrasing) "If someone tells you they are homosexual (i.e. exclusively attracted to the same sex), do you believe them or do you assume they're wrong about their sexual orientation and that you know their sexual orientation better than they do?" So there you have it: (1) gender identity is immaculate and unquestionable, (2) homosexuality is both a choice, bigotry, morally reprehensible, and questionable. Don't believe people when they say they're gay, but you better not question them if they claim they're trans.
