Actually, on a slightly different tangent, I've noticed how authors and "experts" either seem to pout or freak out when the CoS doesn't meet their proper expectations and doesn't confirm the stereotypes you've listed.
Yesterday I got to skim an old book by that pitiful anti-D&D crusader Pat Pulling, who has worked tirelessly (and idiotically) against role playing games, heavy metal and punk music, and devil worshipper ever since her son committed suicide and she found D&D things in his room with a strange suicide note that didn't even cite D&D. In one section of her book, she mentioned LaVey and the Church of Satan
, but added that "many people" do not consider "them" to be "real satanists (sic)."
My mom got me a book recently about the weird legends, people, and attractions in the US, and it had a blurb on the Black House and LaVey. That whole section was practically devoted to "debunking myths" about LaVey and the CoS. I noticed that no other section of any other person--be they Emperor Norton I or the Underdog--was so aggressive about "debunking myths" or what have you. The thing that intrigued me in this case is that this book is effectively religiously apathetic and playful--it cites places named for the devil, and talks about devilish myths of all kinds, and is basically secular. But, something prompted them to be very aggressive towards the CoS.
So, slightly off the topic, and I apologize for that. The thread just triggered my memory. Everyone else has already jumped on the other things worth bringing up.
