This post by Ron Bailey on whether or not parents might do things to help ensure that their offspring are straight reminds me of this post of mine from a while back:

Suppose we find that there is something different about the brains of gay men and women (a proposition for which there’s already abundant and growing evidence). If we can come up with an affordable, painless therapy that “fixes” this and converts them from “gay” to “straight,” should we a) allow them to take advantage of it, or b) forbid them from doing so, or c) require them to? And should “straight” (i.e., exclusively heterosexual) people be allowed to become gay, or bi?

These are the kinds of issues that separate me from conservatives.
