Smedley, You posted opinions, which is ok, but can you support them. They are pretty polarized emphatic statements.

Don, "The brain research that led to the discovery of the differences in the hypothalamus of heterosexuals and homosexuals definitely establishes that there is a physical component. The question raised is "are these differences the cause or the result of a particular gender orientation?" This question has yet to be answered, but researchers are still working on it."
Note the question at the end of that paragraph you posted"The question raised is "are these differences the cause or the result of a particular gender orientation?" This question has yet to be answered, but researchers are still working on it."
So it appears you were able to answer that question all by your lonesone...and it was only a question that was raised...proving absolutely nothing!
Don, you are wasting our time!
