genes say what color eyes, hair, and skin you have. Genes say how tall you are, whether you're male or female, how muscular you're capable of being, or how mch of a propensity you may have to become overweight. I could go on. The idea that genes say who you are sexually attracted to is not hard to fathom. Sexual attraction and love are two different (but sometimes related) things.
Very few people would assert that a gene and ONLY a gene contributes to a person being homosexual, but genetics have a great deal to do with the likelihood of it. Of course, someone who does not have the genetics for homosexuality may still become homosexual due to environmental variables, but it is FAR less likely than someone who already has a propensity for it. This is not something that is widely disputed among scientific circles.
I think a lot of the resistance to some of these discoveries comes from some sort of human hubris to insist on control over one's own life and choices. Or, in cases where sociological control is conceded, there's a resistance to accept such seemingly arbitrary control as genetics. Of course one's taste in fashion has little to do with genetics. If you can't see the difference between that and one's taste in food, or taste in sexual partners.....you need to think more clearly about it.
