Disgust's Pet Peeves:
Brother Shamus, this gets at another topic you raised, and were right to raise. See pic.
Some people who say Satanists are born, not made, are intuiting the essence of Disgust's Pet Peeves and furthermore are intuiting the universality of these peeves among bona fide Satanists. For my part, I've never met anyone who seemed genuinely Satanic who didn't feel disgust when in the presence (or even just at the thought) of these characteristics.
The alert reader will remember "pretentiousness" from LaVey's Nine Satanic Sins, and will also quickly see that "obstinacy" and "philistinism" are renamings of "counterproductive pride" and "lack of aesthetics" from that same list of sins. Meanwhile, "idiocy" is a synonym of "stupidity" but has a very specific implication of incurring risks or costs for the sake of insufficient or nonexistent benefit. "Expending all those resources to develop a product no one will buy is the height of idiocy!"
