People have to fudge their beliefs. No. There’s no way to be an Agnostic Satanist.

I would be considered a "Satanic Agnostic". I don't believe in a physical person known as "Satan", but I do agree with the philosophies of the satanic movement.

Like others said, no actual belief in deities or demons is required for many satanists.

Tenets from the Satanic Temple:

-One should strive to act with compassion and empathy towards all creatures in accordance with reason.
-The struggle for justice is an ongoing and necessary pursuit that should prevail over laws and institutions.
-One’s body is inviolable, subject to one’s own will alone.
-The freedoms of others should be respected, including the freedom to offend. To willfully and unjustly encroach upon the freedoms of another is to forgo one's own.
-Beliefs should conform to our best scientific understanding of the world. We should take care never to distort scientific facts to fit our beliefs.
-People are fallible. If we make a mistake, we should do our best to rectify it and remediate any harm that may have been caused.
-Every tenet is a guiding principle designed to inspire nobility in action and thought. The spirit of compassion, wisdom, and justice should always prevail over the written or spoken word.

Put the material world in front of all things...Which, is just want the Peoples of the Book do...Yeah, I don't get it now either. LOL.

Did you read the group description? Have you ever looked into Satanism or you basing your views on what christians say about it?

Satanists don't worship Satan, they don't even believe in it. Satan, to them, is a symbol of rebellion against religious indoctrination.

In the bible it was Satan who refused to bow before god. Satan represents rejection of oppression.

The Satanic Temple (not the LaVey sect) refers to Satan as a symbol of individualism and rebellion against authority. They promote religious freedom.

LaVey Satanism and its derivatives neither worship nor believe in a personal devil, they are mostly just provocateurs with that.

In any case there are agnostic theists of various stripes. Not common, but they exist.

I was a member of Anton LaVey's Church of Satan back in my late teens/early 20's. The COS was a decidedly atheist organization. Most of the get-togethers were philosophical discussions with occasional "rituals" that were mostly a way of making fun of the "born again" folks who were just starting to become a "thing." ,

Good question. I've been wondering the same thing.
