Can someone, anyone, including you Eterna, provide a credible source claiming that choice or environment cannot change sexual orientation? I've provided more than a few claiming it can. Waiting on you guys. If you have such a source that is.

I guess c/p'ing and googling the title was too hard or something.

Just for kicks, here's a pretty new study claiming that genes have little to do with initial sexual orientation. It claims that environmental factors trump all when it comes to initial sexual orientation.

Environment plays the largest role in initial sexual orientation, with genetics playing only the most minor of roles.

Learning and conditioning (societal, personal, etc) play a large role in sexual orientation.
I'll add more in a moment.
