With all due respect, I don't believe you're being honest here. And that goes to my point about people wanting race to not be a social construct. I believe you're lying to yourself(or just lying to me) that you wouldn't be crazy surprised in either case.
> But the real, underlying question that is the base for "many people really, really don't want race to be real" is, "So what?"
Exactly. You don't want race to be real, you think it might be misused if it was real, and so you argue that it isn't real. That is not a compelling basis for an argument. A good argument for the earth being round is not that you're scared of people punching you in the nose if you say it is flat.
> Now, neither you nor I particularly care whether homosexuality is genetic or a choice, but I hope you can see how someone who has to respond to "So just don't be gay!" might prefer one over the other.
Yes, I can see how they would prefer that. But it has no bearing on the reality of whether being gay is genetic, or a choice, or possibly both, and really has no place in scientific analysis of sexuality.
