Yeah, that's true. It is a great song, and leave it at that.
The "documentary" in question, is called "Freddie's Love," I think, which is a rehash-type of show, along the lines of an E! True Hollywood show. Not exactly the final word on anything historically accurate.
I do think people react violently when the idea that some of Freddie's songs may have anything -- anything -- to do with his being a gay man. I think there's something more than slighly phobic about it. If it was some hottie gal, it'd be brushed over a little more easily. But then again, I'm a little more touchy about these matters.
