Homosexuality is completely valid just like heterosexuality. Homosexuality has been proven in hundreds, even thousands of species. Homophobia is only found in one. You may say that is because we have intelligence, but attraction is not a choice. It is a reaction of chemicals and chemical effects going on inside the body. You cannot tell your body to initiate this process. Since attraction is uncontrollable, it's easy to prove that any sexuality is valid whether heterosexual or not. To try and prove that homosexuality is forced and not real, is actually quite challenging because scientifically, there is no such evidence. Of course personal belief cannot be used as evidence in a valid arguement, but I am able to accept if your beliefs are not the same as mine.
