Fiiiiiine, it’s not the *exact* same bodies. I’ll give you that one.
However… they can sure get very similar, to the point where you literally won’t even be able to tell the difference unless you’re getting very intimate with the trans woman in question, if you know what I mean.
Other than that? The quoted trans woman is right, and isn’t saying anything objectionable. Especially if her “same sex attracted” complaint means what I think it does: that she’s saying that the sort of people who have a habit of heavily emphasizing "same sex attracted” as their attraction criterion might be, well, transphobes. Though the phrasing is kind of ambiguous so it isn’t entirely clear. But if she meant it in a more absolute sense, like “having a body type preference is transphobic”, then I wouldn’t agree with her.
Also, I do agree with what she said afterwards: “A cis man who’s with a pre-op trans woman isn’t gay or even bi.”
A lot of folks struggle with seeing how that’s the case, but it really isn’t odd when you think about it. I’ll explain:
1) How often do you see someone’s genitals anyway? For most people, sex with someone comes after already having known that person for a while, and being attracted to them. If you find a woman attractive, you probably haven’t yet seen what’s between her legs, have you? (ditto in the other direction btw., regarding attraction to trans men)
2) Once you do know of or see what she has down there, does that mean you’ll just instantly lose all interest in her? Maybe, though in that case I’d recommend you do some soul-searching and ask yourself why. That said, there are people — like me — who are exclusively attracted to women and who don’t really care about what genitals she has.
So what if she has a penis etc.? It’s just one part of a much greater whole (not just the rest of her body, but also herself as a person whom I like).
I’ll also flip that: If it were a trans guy, could I find him attractive? Would the fact he has female sex organs down there in any way help, let alone suddenly kickstart an entire attraction towards him? Of course not. Why would a vagina etc. somehow get me to be attracted to a man?! That makes no sense. Especially if he looks like a dude, sounds like a dude, acts like a dude and sees himself as a dude.
Sex organs are but a small part of the whole (though one I still appreciate!). They are not this huge, all-important factor that makes or breaks my entire physical attraction — let alone emotional attraction — towards a person.
Of course, I recognize that for a lot of people this is different, and the question of sex organs matters to them a lot more. That’s fine. But I hope those people also respect and recognize the validity of my own view on this matter, and don’t base the entirety of their assessment of someone’s sexual orientation merely on what sex organs that person’s willing to work with. Sexual attraction is so much more than just “peen or vagoo?” — it consists of a million little things, and isn’t nearly as reductive as TERFs and the like want it to be.
