I'm sure in a lot of ways I agree with you, but not on this particular article. I don't think the name matters. The essence does.
Don't let the name fool you. WBC is as Satanic as they come.
Let's take this and plaster it all over the place until every prospective satanist first tries to get the magic eye to show a schooner before attempting anything else.
The essence is always there when the argument, "______ are just trying to piss off people that do things they dont like" can be had. The center piece of satanism lay therein, but...
What I have problems with is applying that essence to a group. Because after the WBC, you have Ruby Ridge, Waco, FLDS, Eco warriors, jihadists, skinheads and every other 12 Monkeys like attempted societal subversion.
The actions of smashing social taboo is there but most of the doers are as wired to following, acceptance as reward, and as plastic as anyone else.
The line I like here, and use often is:
"A person is smart, people are dumb panicky dangerous animals and you know it."
In analogy it works.
A person's societal transgression in their establishment of autonomy is satanic, but a groups societal transgression, an effort of like minds, fails to meet criteria of fierce individualism even if its source is.
Take "annoying liberal faggots". On a personal level it is perfectly satanic to be triggered by said annoying liberal faggots, but ones person ironic support of Trump can quickly lead to a false party line of "You must be annoyed by liberal faggots too" rather fucking quickly.
And the once hilarious decision to hock Trump merchandise leads to something approaching a conservative party line that borders on bizarre. I bet if you did a visual mapping of "Things online satanists think" in a spectrum of extremes it would look still like a school of fish. They are like fashion trends and it is fucking hilarious. All of a sudden mustard yellow is in.
Everything gets diluted and deluded after a the initial browncoat reflex.
