Since this was brought up on your show this week, I wanted to mention it because I have never seen any actual confirmation of this and only sourced on some outdated fan BB wiki. It doesn't seem to be anyplace else, and especially if he had made appearances at pro-gay events like the rumor goes, I think we would have seen press releases and even photographs from those attending.

At this site, though (who knows how reliable this source is, but it seems more reliable), this wiki is mentioned. He claims it's a hoax perpetuated by this outdated wiki.

I also thought it might be worth pointing out that the electronic music duo Matmos has a member named Drew Daniel who is gay. So maybe info got crossed that way by a dumb internet search, or the hoax was deliberate and this little tidbit adds pseudo-credibility if you're searching for a gay Drew Daniel and end up with a bunch of hits.
