Continuing my comment.

In any case, I'm sure you'll be quite happy when the meeting is opened with an Islamic prayer.  Or haven't you thought about that?  Or is this simply about allowing your religion and no others?

But over to "Satanism" - hate to tell you this but people like the Satanic Temple do not worship demons.  Their beliefs (I hesitate to use the word religion since it doesn't involve the worship of any sort of supreme being) are focused on ethical behavior.  They're a political, not a religious organization. The group utilizes satanic imagery to promote egalitarianism, social justice and the separation of church and state.
