Nah, it relates to many subjects. It isn't homosexuality in general but you are right when you say that there are a lot of similarities. It is just basically symbolising the struggle for acceptance in a society that is mostly single-minded. Anyone who is perceived as "different" finds it hard to fit in, whether it be homosexual or the struggle that many african americans still have to fit into what a lot of faggots like to call a "white man's world". It could also apply to refugees, migrating to a new country and finding it hard to fit in with society and get a decent job or something.
