Here's what I personally think:
Genes constitute only one of the many key influences on behavior in addition to environmental influences, personal choices, and interpersonal experiences.
So-called "sexual orientation" is "fluid," not "fixed" and often changes throughout a person's life.
In fact, some studies found that eighty percent of males who reported homosexual or bisexual feelings as children later identified exclusively as heterosexual.
So, To be clear, the research will continue, and this report isn't exhaustive of all the studies out there, but it is enough to prove that the science isn't settled as we're often told.
Therefore, those using the levers of cultural power to impose this new vision of sex, marriage, and humanity aren't driven by, nor will they be unconvinced of their vision, by science.
