Personally, I think it's ridiculous to say someone can't write about, sing about or otherwise creatively champion a cause if they themselves don't fall into that category. So he's not gay; so what? The cause obviously means a lot to him, and he obvious has very strong feelings about it. The song itself is beautiful, and the music video is heartbreaking (seriously, I cried the first time I watched it). I don't think it's fair, or practical, to pick and choose support. This song has brought media attention and an outpouring of support for the LGBT cause and community. And in the end, that's what matters, not whether who sang the song was actually gay or not.
