Just out of curiosity (and I don't mean to derail your thread or anything) have you ever heard of The Satanic Temple? They're completely atheistic as well and have some really excellent social initiatives, mainly fighting for the separation of church and state as well as individual liberty here in the US. I encourage anyone to go read their 7 Fundamental Tenets if you have the time -- they're a hell of a lot more reasonable than the Ten Commandments. TST was recently allowed to give an "invocation" at a Pensacola FL city meeting, which was hilarious -- you can find it on Youtube. And they're planning on bringing "After-School Satan Clubs" to elementary schools in an effort to combat all of the "Good News" Christian clubs and give kids an actual choice. The clubs aren't about worshiping Satan at all, but focus on teaching kids about free inquiry and rationalism. Good stuff.
Once you bring Heirarchy, tenents, rules and all that non-sense crap inside a philosophy (specially in a VERY elite and individualist philosophy such as Satanism), it's no longer a philosophy. But just another cult.....another way to make money.
You don't have to join the Church Of Satan or The Satanic Temple to be identified as a Satanist, nor you need a sporting-red plastic membership card.
You just have to live your life according to what you learned and that's all.
Plus, in a age where the Internet is full of information and resources, anyone who wants to learn more about a specific subject can find ANYTHING they want, from complete books to articles, without necessarily having to be part of an organization, or having an actual organization proselitizing and promoting their stuff, down in schools or people houses.
Plus, what's with the "After-School-Clubs"? Sounds so familiar to "proselitism" to me. And proselitism, at least in LaVeyan Satanism, has always been a big NO-NO.
What they're trying to achieve with that initiative? What they're hoping to change?
I highly doubt it will ever change people minds on the all "Satan" stuff. Satanism will always remain the most feared religion of all. There's no way to change that ever. And it will always be plagued with misconceptions and hyper-criticism from opponent religious groups, regardless of the status and politeness of an organization.
Good luck to them. But I don't see that move as a great way to promote Satanism at all.
