I see Apatow as being willfully ignorant of the pernicious messages in his work and thus malicious in that he refuses to acknowledge the problems, since they have been repeatedly brought to his attention. Willful ignorance can be a form of maliciousness when it comes to these sorts of situations, because one is willfully trying to excuse and/or absolve oneself of sexist/racist attitudes by pretending those attitudes don't exist.

I can't see how the episode revealed a distrust of organized religion-- Asatru is hardly particularly organized, Greek/Roman worship is exceedingly rare and fragmented, and there was no mention of practitioners at all in any case. Besides that, the Christian deities and spirits were apparently blindingly overpowering (to the extent that a manifestation of the Hindu godhead had to be saved by Sam and Dean), which certainly says something about Christianity, which, TBH, is one of the most organized of the religions mentioned in the episode. I'm trying to ascribe this to "they were trying to rip off American Gods and failing miserably" instead.

Yes, it is! I apparently have no SPN icons except for grumpy-lady ones.
