Theological substance and matters of taste aside, no one can deny that Anton LaVey designed the perfect product to satisfy a demographic that wasn't being served, and he sold it brilliantly.
I don't see much of a "product" here. It's a very lazy sort of religion that's founded on the basic tenet of "do whatever you want whenever you want"...just dressed up with fun "halloweenie" decor
Don't forget "being weird makes you not only equal to but better than everyone!" Anton LaVey framed every eccentricity, perversion, and flaw as secret evidence of superiority. Anybody can make you feel like wanting girls to pee on you is OK, but only Satanism will suggest that it makes you a master of the Universe.
