Over on Facebook, where I said, "I've been paying too much attention to bad things lately, so I'm going to pay attention to good ones for a while", I just got this comment: "thanks for your inclusion of a gay character in your young adult fiction works, Elsewhere and Nevernever, and for having the other characters accept and defend him. As a young gay man I was pretty happy to see that...You can chalk that up as one good thing!"
I always grin when I say that when I write fantasy, I just write what I know, but it's true. I've had openly gay friends since I was fifteen. Why would I leave them out of my work?
