Fruit Flies in the Castro

The boffins at University of Illinois at Chicago have figured out how to make fruit-flies gay, and how to turn them back again. It's very interesting to me because the human gay population for years argued that being gay wasn't genetic, because they didn't want to suffer Mengele-esque attempts to be cured. I always thought this was an unfortunate policy, since the argument "hey, this's how we are, and that's just the way it is" is a much better argument for acceptance vis-a-vis natural rights, &c. than "hey, it's a valid lifestyle choice" (since anything that's a choice is subject to slippery-slope arguments such as whether polygamy/polyandry, consensual teacher-student relationships, &c. should also be allowed). Ammunition for the "that's nature, get over it" crowd has just come through with variably, tunably gay fruit-flies -- if the mechanisms that determine sexual orientation become sufficiently widely understood, then those who feel that things should be otherwise can take it up with their creator, whereas the rest of us can move on and start making the appropriate societal decisions.
