Jeremiatron 1000:
Cybernetic Prophet

Repent sinners! The hour of reckoning is at hand!  While the coming out part of Dumbledor took many by surprise, be warned! Seven more fictional characters will come out the closet in the coming weeks. Homophobes will have a collective stroke, while hardcore literary theorists  will express chagrin that an author has handed down a character's identity extra-textually. (A few people will also be angry that  Holden Caufield was gay this whole time.)
