Isn't the hostility of these creators analogous to someone over on customers_suck ranting about the asshat customer who ruined hir whole shift at the store with an hour of annoyingly stupid questions?
Substitute "my shift tonight" with "the Merry Gentry books", and substitute "this asshat tried to return an item without a receipt and it turned out he didn't even buy it at this chain to begin with" with "if you don't like the books, don't read them"... don't you wind up with Laurell K. Hamilton?
(... OK, that's not too good an example, because man, her books really /do/ suck more than a purpose-built nuclear-powered ass-sucking machine. But you get my point, yeah?)
What do you think, am I off-base here?
