It would be interesting if they did find the "gay gene". Then people can start prenatal testing for and then aborting genetically damaged (aka. "gay") fetuses. Let the pro-abortion, gay agenda promoting liberals choke on that one.
The genetic engineers and politicians of the future might come up with some requirements to match their agendas - 95% homosexual births, 5% "breeders" - artificially inseminated, of course (see "Brave New World"). This way the genetic makeup of the race would be controlled.
Do you think that the liberals would be saying "her body, her choice" then?
I doubt it.
People who do not believe in abortion would treat this matter in the same way as if they were going to have a baby with Down's syndrome (or any other diability). It may be a tough road ahead, but with love, patience & faith, any decent human can rise ro the challenge of good parenting.
Liberals would be more likely to abort "oppressive patriarchal heterosexual blobs of tissue" than gay babies.
Wait a minute. Liberals wouldn't be upset about having gay children, so that situation wouldn't produce a conflict. Anti-gay, pro-life conservatives, on the other hand would have to reconcile one value against the other.
There are gay men who are against abortion. For one thing, they're never going to want one, and they're never going to feel a need to pressure anyone into one.
Another point is exactly the one you raise above: if/when genes correlating to increased chance of homosexuality are found, women might choose to abort their maybe-gay unborn children.
Another reason some gays are against abortion is because it's sick to kill human beings like that. Of course, most FReepers wouldn't associate gays with any sort of conservative values, but that's only because they're so interested in labeling gays as "bad guys" opposed to everything good and decent.
