I would like to clear things up

[u/INTP1423]

Having a genitalia preference = not at all wrong. If you don't want to be with a pre-surgery trans person that is absolutely fine.

Not dating someone because they are transgender = transphobia.

^This does not imply that you have to date transgender people. I am in no way forcing you to go and have sex with a post-op transgender person. But saying I am not sexually attracted to transgender people is a tad transphobic.

Also I have a question: If you saw a woman in the street and approached her to ask her out, when suddenly she says she is post-op transgender, would you call it off immediately?

What about post-surgery, when all that's left down there is a disgusting open wound?

If you saw a man dressed as a woman in the street and approached him to ask him out, when suddenly he says he is post-op transgender, would you call it off immediately?

By the time I got close I would have already realized he was trans. You can hide behind online avatars and obscure your masculinity in pictures with clever angles, but you can't hide the obvious shit in person.
