Since being homosexual is looked upon by society-in-general (all societies have taboos against homosexuality in one form or another), and homosexuality does nothing to perpetuate the species, then homosexuality can be looked upon as an undesirable trait. If a trait is undesirable, and can be corrected, and the recipient of said 'cure' refuses treatment, then what do you call that person? How do you treat that person?
"The key factor is that these genes both influence homosexuality in men, higher fecundity in females and are in the maternal and not the paternal line,"
The same trait which may cause homosexuality in men also increases the chances of their female siblings to be fertile and bear children.
Beyond all that... you're assuming that homosexuality can be treated in the individual 'suffering' from this condition. Gene thearpy doesn't work that way... hell, it barely works at all, with the research and application of gene therapy being in its infancy now. In addition, the gene seems to passed down through the women and not the men. If you treat all male homosexuals of a generation, the next generation will still have the same chances of producing homosexuals as if you had not treated a single man.
Gene therapy is not a magical blue pill which a gay man would take twice a day with meals and expect to suddenly become heterosexual after a 3 month treatment.
The treatment would have to begin early in the foetal development, and THAT may not even be early enough. Successfull application of gene therapy to remove homosexuality would have to begin with pre-pubescent females by treating their ova. This is where the gene lays and how it causes homosexuality...through fertilization. You'd have to treat all women (only those with the gene providing that you can test for it and that all women are tested before they begin procreating).
We don't even know if its possible to treat this gene without harmfully reducing the fecundity of the women treated and their female children for generations to come. Imagine removing the homosexual gene, but suddenly... fertility in females drops to below 30%... that would be disasterous.
Beyond all that, you're only likely to see a change in the homosexual population after all existing homosexuals, including all those born before the treatment began, die off. This would only be in the more affluent of nations, because the large-scale treatment of all women in a population for several generations to come, is an expensive attempt to say the least.
It's not even a guaranteed treatment and couldn't be testeable for at least 15-20 years after the initial treatment, as you'd have to wait for the first post-treatment generation to reach an age where they're conscious of their sexual awareness before deciding if a treatment was successful.
So...the question should not be "what if homosexuals refuse the treatment?" but rather "What if women refuse to take a treatment which may or may not protect their children from homosexuality but, at the same time, may or may not make their daughters infertile?"
