I'm quite surprised if you can't figure out how what I said relates to what you said.
If you want to give people "choice", and are capable of giving your kid some sort of designer sexual orientation, making them strictly heterosexual or bisexual is an extremely silly thing to do, especially since binary sexual orientation is barely even naturally-occurring in the first place.
I gotta say, I have absolutely no idea what you're trying to communicate here, probably why I couldn't figure out how it relates. The core seems to be that I have no idea what you mean when you say "binary sexual orientation", I think. Care to define?
You said:
The idea that binary sexual orientation gives anyone a realistic amount of "choice" makes me laugh
While I have no idea what you mean with binary here - The choice it gives is pretty much exactly limited to the one I brought up, and its pretty crappy! But it doesn't change the fact that heterosexuals have slightly more choice in total - they can have a baby as a couple naturally, use a third party, artificially inseminate, or adopt. Homosexuals cannot do one of those. It is a REAL choice that homosexuals don't have. I don't think its a particularly valuable choice, all told, but it exists. And bisexuals have what is essentially a
doubled pool of potential sexual partners. That is definitely a lot more choice there.
do the ideas that we'd be better off with less diversity, or that sexual orientation, even if genetic, is controlled by some easily toggled mechanism.
Did I say any of this? Really? Because I agree with you those things are desireable, and that its unlikely to be easy or desirable.
I didn't agree with you. If anything a homosexual society would probably be a lot more peaceful and gender-equal, as well as maintaining its population at a more sustainable level. Maybe.
Whoosh. That's the sound of you completely missing the point. The things you said had nothing to do with the things I said. Period. There was no overlap. I say "Heterosexuals can have children that are genetically the offspring of both parents, homosexuals can't." You say "Homosexuals can do these others things". Yes. They can. And your point is? Heterosexuals can do those things to. If you want to counter my argument that heteros have a single choice more, you need to actually counter it, not ignore.
