If what he found was what he wanted, and he did things he enjoyed, what does it matter where those parts came from? He met a woman, he liked a woman, he screwed a woman, and he presumably had a good time, period dot.

That's the crux of this particular argument for me. Being turned off by someone's body parts? Normal variation in desire. Being nauseated by the idea of the source of those body parts challenging your straightness? Homophobia and transphobia, plain and simple.

This does not make those emotions not real, to be clear. Emotions are emotions. But every one of us has the personal responsibility to handle our own emotions appropriately, and examine whether they come from flawed reasoning or bigoted assumptions.
