I don't often experience gender dysphoria,
but when I do it's over things like this.
All my sympathies.
So, it's a really, really bad idea to actually
say this, but the next time he gets all 1 Corinthians 11 on you (a rather subtle and complex passage*), you could point out 1 Corinthians 7.
(*Corinth was rather cult-like and - probably - was encouraging initiates to leave their spouses for the Church, not welcoming couples and families, that sort of thing. It's impossible to be sure because so little historical record remains. But the whole "you don't actually get a second shot at marriage" thing is found throughout the New Testament and
quite explicit in the Gospels.)
Don't actually bring this up. Repeat: do not. You will reduce a (possibly) healthy fight to mere debate. Don't let him drag you down to his level - he will win with experience.
No, if you're going to fight, fight like a woman. That is, fight dirty, with emotional judo. Not dominance but indomitability.

I personally dislike the stereotypical "is this about X?" parry. Sure, it gets your opponent in a position where they're compelled to answer yes or no, but it's a little too passive-aggressive. I prefer to own my opinions: "I think you're worried that I'm not tough enough." Or to express confusion over assumptions. "Why would I wear that to an interview?" (
no aggression in your voice) or "Of course not; that clip is too cute."
If you do get angry and can't control it, it's better to own it. "I'm angry." "I don't know why, but I do feel like you're trying to reject who I am."
*sigh*
All this reminds me why it might be better to be out to my father. Because as it stands a good fight could make me say, "are you saying I'm not a man?" in response to gender-policing. And there goes the can of worms.
