This reminds me of something I read on the blog A Collection of Unmitigated Pedantry, which was the simple observation that medieval people believed their religions, whereas George Martin writes a world that has the trappings of being medieval, but lets the villains perform un-medieval blasphemies without being brought to heel by the vengeful pious. Calling an all-father deity a transvestite should be highly offensive to all around at best, if not cause to step backwards out of the splash zone.
