For the last few years, one of the most hotly debated topics in America has been the question of whether homosexual couples should be able to get married. Specifically I will discuss the issue of whether or not homosexuality is a choice, as it has become a major part of the debate. If it were a choice, then gay marriage would arguably be unnatural and banning it would be more defendable. However, I believe that the idea of homosexuality being a choice is ridiculous. True, one's sexuality is likely not entirely determined by one's genes. The textbook tells of an experiment which shows that even identical twins, with 100% identical genomes, can often have different sexualities. However, this only proves that sexuality is more complicated than simple DNA, which has nothing to do with choice. Even if sexuality were entirely determined by environment, it would still be chance and not the decision of the person in question. I have never heard of a person of any sexuality who chose to be that way, and I am fairly certain that few such people ever existed. Even the stories in textbook of gay men who were 'corrected' to be straight turned gay again within a matter of years. So I don't think there can be any debate about the fact that homosexuality is not a choice.
