Eeeeew!
I have no opinion about your family or your anecdotal experience and the conclusions you draw form your personal experience.
I am simply saying, there is no scientific basis for the conclusion that homosexuality is of organic origin.
Any assertion to the contrary is false, that's all I am saying.
I would have to disagree. Statistically significant differences in brain function between heterosexuals and homosexuals have been documented in peer-reviewed literature. Animal studies have shown that sexual behavior can be drastically affected by prenatal hormone exposure. Even anecdotal evidence such as MAWG's can can be "scientific" evidence if it is documented to be statistically significant, which some twin and sibling studies apparently have.
Now, that does not go to say that a person having some particular "organic" element is certainly homosexual. But it does suggest that there is more to it than simply "free choice."
I do believe the hypotheses was that men can be born with a female brain and vice versa.
