I've seen this following phrase all too often: "Oh, I accept transsexual women, but I'd never date one! I'm just not attracted to them, that's all!!"
The problem with this statement is that it contradicts itself inherently. It's a bold claim to make, but I've had this discussion many times, and talked with many people, and after a few more questions, the result has always been the same. They try to dodge it by saying "What, can't I be attracted to what traits I like?!!?" avoiding the underlying problem with their assumption. After a little digging, the result is always the same:
"Well, they were male. Once I know that, I'm not attracted. I'm just not into men"
The problem is the last statement. The statement "I'm just not into men" COMPLETELY invalidates any acceptance you've claimed. Whether or not you can put on a mask and tolerate them, whether or not you can humor their desired pronouns. That's not 'accepting them', that's humoring them. It's tolerating them.
Because it's not hard, really, to tolerate a trans person. An extra letter added or subtracted from a few pronouns, a few minor language changes.... and you're pretty well able to appear like you're a trans ally!
Except that you don't 'really' accept them. You harbor your own contradictory prejudices that, while you think you know 'the truth' of their gender, you'd rather play nice.
This is one of the purest forms of lack of acceptance in existence. Ask yourself, would you date a transsexual woman? (If lesbian/straight male)? Would you date a transsexual man? (if gay/straight female)?
Why wouldn't you, if you said no?
It's a question that's VERY telling of how much you really accept a trans person. The science still supports transsexualism, but if you cling to prejudices, even if you hide it well, you're not truly accepting of trans persons.
(P.S. Orangeban - I will get to your question - I was fired up over this one and had to write. fear not! Also, if you feel safe, drop an email in the comments section if you would like!)
