I think I get it now. 
"Anton LaVey, who has been referred to as "The Father of Satanism",[75] synthesized his religion through the establishment of the Church of Satan in 1966 and the publication of The Satanic Bible in 1969."

So the organization of a church and having a book could meet the criteria of a recognized religious organization. Everywhere I've looked seems to contain only opinion pieces in a 50/50 split. 
Personally I agree with doing away with it all together but if it's going to be done it should be done with positivity and without tribulation and disharmony. Spirituality is very reactive and obviously hailing Satan lol did not create a peaceful environment. I seriously doubt positivity was the satanist intent either, more for shock value, disruption and attention.
