Are you aware of who WROTE it, Dr. Guy? Freddy Mercury, a pretty flaming homo!
So? Liberace played some of the best Piano solos the world has ever heard. Elton JOhn wrote some of the best songs ever. Neither was making "a statement", just creating music for the world to love. I dont see why we have to now reserve the word Gay because a segment of the population decided that was the term they were going to use to describe themselves - outside of the origin of the word.
if Freddy Mercury wants to tell us, through whatever medium he chooses, that the song was meant as a gay Anthem, then we can believe him. But that is not going to detract from what the song says (nothing about sexuality), or how the rest of us hear it.
Not all "Straights" are writing only heterosexual anthems, and not all "gays" are writing only homosexual anthems.
