To this I have to say, well, duh. I'm sorry, but the older, unattached, distinguished English gentleman thing was a good hint. The flaming pet, the purple velvet robes, and I'm not even going to start on a deconstruction of the words "Head Master" - let's face it, there's a reason Hollywood initially tapped Ian McKellen for the role.
Did I just say "tapped Ian McKellen"? That may have been over the top. Sorry.
But let's look at the current actor playing Albus Percival Wulfric Brian Dumbledore - Michael Gambon. His last major role was in The Good Shepard, where he played Dr. Fredericks, an older, unattached, distinguished English gentleman. And professor. And gay man.
I think we're seeing a pattern here. The best part, as far as I'm concerned, is that we've named one of the family cats Albus. (Yes, the other one is Flitwick.) Great - I have a gay cat! I can't imagine anything cooler.
The best part of this bombshell will be the inevitable reaction of the Christian Right, now that they know that Harry Potter doesn't just have magic - it has GAY magic!!!
I've been a fan for years, but JK Rowling is my new hero.
