There is an increasing amount of evidence that both sexual orientation and gender identity are the result of congenital factors relating to the hormonal environment in the womb.

No there isn't. You can't support that statement and you know it.

There are differences in brain structure, and it is very doubtful that those differences in brain structure are due to learning experiences. The hypothalamus is the site of most of those differences, and based on biological research on animals, the areas of the hypothalamus are linked to the control of sexual behavior.

Besides, what I have found in a study of the literature is, the sexual behavior characteristics are in place, well before puberty. Many researchers report many gay and transgender children know they are different by age 2 or 3.

Again, I will offer a word of caution about quoting Paul Cameron. I have serious doubts about his integrity, because he fits the pattern of other cases of research fraud that I have seen in a variety of scientific disciplines.
