Please don't stop! That's not what I mean at all. :-)
Bear talks upthread about seeing yourself in fiction for the first time -- her New Amsterdam was that for me, and I value it irrespective of the author's gender and orientation and whatever.
I do think that we would see a different and also-valuable set of stories told if we saw more queer men writing queer protagonists, and I am feeling the lack of those stories somewhat critically right now.
Good fiction is good fiction, and everyone will have to write and publish a hell of a lot before my appetite for good queer characters is sated. :-)
