You know Maus[0]? It's a comic book about Disney animals. Isn't that just laughable? Wouldn't teaching such a thing in schools--with the aim of imparting serious lessons--be "ludicrously off base"?

Derision for fan fiction and/or Harry Potter can't be the beginning and end of your argument for why HPMOR isn't a good book to introduce nerdy school kids to a handful of valuable ideas.
