The fact that homosexuality exists not just in humans, not just amongst the ape family of which human is a branch, not just amongst mammals, and not even just amongst the phylum that includes vertabrates, but in other phylums in the animal kindom such as the arthorpods as well, strongly suggest there is evolutionary pressure to preserve this behavior. This means any gene(s) reponsible for homosexuality is a well vetted, if perhaps subtle, evolutionary and survival advantage for the population that possesses it.
So any effort to remove it from the population is not curing anything, but introducing a defect by removing a gene(s) that demonstrated its value to the population by surviving possibly for as long as 6-800 million years since the ancesters of phylum of chordates to which humans belong, from the ancester of phylum of arthropods to which gay houseflies belong..
