The other thing that I noticed in a lot of comments in the spoiler communities is that I think quite a few people only read the epilogue and then the spoilers for the rest of the book. They hate it but they haven't actually read the whole thing - moreso at the its_a_fake community, but I've seen several comments along the lines of "Well I've just read the epilogue, and what a pile of crap, there's no way this is real." Well yeah, the epilogue sucked. But in the context of the book as a whole it's hardly that big of a deal.

Plus its the HP fandom. People are insane. Completely fucking batshit insane.
