A little more thoughtful and intelligent response to this article than most. Bravo! But unless you are in the habit of rejecting all legitimate science due to religious beliefs (oh now THAT would be a RARE thing here, eh???), then you must keep your mind open. It is the scientifically appropriate thing to do. Whether homosexuality and genocide are to be treated equal, however, is entirely up to you.
I guess the problem is in how we define legitimate. Science can take a legitimate stab at what causes homosexual desire. But science is being dishonest to deny the anatomy of a person in the process of analyzing the data. A woman with a womb, ovaries, etc. is obviously not born homsexual. She may have sexual thoughts and desires towards other women, but to interpret those desires as normal is "science" ignoring science.
