Oh yes, I get that. But, to me, the problem is not the definition of "hate" (e.g.; you cannot "hate" something that doesn't exist), but rather the definition of god. By definition (to me, at least) "god" is a fictional character. I'm free to love, hate or be indifferent towards that fictional character, but my feelings or lack thereof have no bearing on its existence as anything other than imaginary.
ETA: of course, the equivocation is on "hate". My definition allows me to hate fictional characters. KK inserts her own definition that eliminates fictional characters and can then say, by using her definition, I MUST think those fictional characters real. Problem is, that lets in a lot of fictional characters, not just one.
