Homosexual Phobia?

I have noticed a linguistic peculiarity that most have come to accept but may be signalling a shift in opinion. We have racists, sexists and homophobia. Racist and sexist both refer to an opinion or state of mind, whereas by making the dislike of homosexuality a phobia it frames it as a disorder. While as a culture we despise those who hate other races, at least we admit that they can come to that conclusion using the faculties of their mind. The word usage for those who hate homosexuals though implies that anyone who comes to that conclusion has a psychological disorder. This assesment of their detractors helps to reinforce their talking point of inevitability of behavior.
