Who needs old closet case Dumbledore when Claire has put together a first-class list of out-n-proud GLBTQ-and-sometimes-Y fiction?
I've got an editorial in the upcoming Horn Book about the outing of Dumbledore, who in fact joins a long line of characters who coulda-woulda-shoulda be gay if the reader so inclines--like Shakespeare in Susan Cooper's King of Shadows as we discussed here a few weeks ago. Or Harriet the Spy. (Or Sport, Beth Ellen, or Janie.) Betsy and Tacy! Frank and Joe! Nancy and George! Or not, too--the point is that characters become your imaginary friends whose lives, loves, and destinies can become what you need them to be.
I'm reminded of 1965, the momentous year when Barbie became flexible. Durable characters always are.
