Hah. What is that? The inquisition? I think I've made my point perfectly clear. You're really not doing your side of the argument any favours.
But fine, whatever: I'd have no problem at all using a different bathroom. As for "guy get-togethers", well, if gender truly becomes irrelevant, then those things wouldn't exist, either.
And as I've said, I don't think I really "identify" at all. I'm just stating plain biological facts, as Beholderess formulated it. Now, if those facts were to turn out to be not quite as plain in fact - now I can't be sure, of course, but I really don't think much of my self-image would change. After all, if I were to turn out as XXY, then in that case I'd have been so all my life already. Nothing would actually have changed.
I'd probably still call myself "male" to others, if only to avoid the hassle of describing chromosomal intersexuality, and list my sex as male in formulars since intersex usually isn't a choice - but I would be aware it's not strictly spoken the truth.
And really, chromosomal intersex people are what, 0.1% of the population? It's ridiculous that you want to base a general argument on that
