It is interesting how just about every credible source, medical professional, and scholar on the subject disagrees with you:
click here ...After all, who would choose a lifestyle that that, knowing the social, political, and medical repercussions associated with it?
Sorry but that is no argument. You might also ask why people choose to be:
* Smokers
* Criminals
* Child abusers
* Alcoholics
...etc...
In fact I enjoy the odd cigar myself. Yeah I know it's bad for me. Should I now blame my genetics?
Just because it's a bad choice doesn't mean it's not a choice.
The APA publishes an undated brochure titled "Answers to Your Questions About Sexual Orientation and Homosexuality." They state:
"...many scientists share the view that sexual orientation is shaped for most people at an early age through complex interactions of biological, psychological and social factors."
First, notice it says "many" indicating that the matter is far from settled. Second, notice that it says "biological, psychological and social factors," indicating that no scientist would say that homosexuality is purely genetic the way left-handedness or eye color is. Homosexuality is determined by one's environment, acccording to the APA, i.e. a learned behavior.
Twin studies have proven that it is not genetic as the incidence of homosexuality never approaches 100% as it would be expected if homosexuality was an inborn trait.
