These are actually atheists who use these types of occasions to try and have religion removed from the public sphere.
So basically they are proposing a choice: either you get rid of religion entirely OR you allow all religions including worship of Satan, and here it is for all to see.
This sort of binary choice is common to atheists way of thinking since they don’t see any one religion being any more true than another since they see them all as make believe. So they are lumping all religions into one. Even though in reality they are NOT Satanists by their own statements, and are just trying to use these occasions to have religion removed from the public sphere by forcing this binary choice on the government.

Note where they describe that they don’t believe in Satan.
I have confronted a few of these folks before and it seems that they really do consider themselves more a political cause - to have their government conform to their atheism or agnosticism. They are truly offended that there is some religious, and specifically Christian norms in government.
Of course, things are more nuanced. Our government in the U.S. was informed by religion. In God we Trust. On Nation under God.
Separation of church and state was proposed by the US founders to protect the church from being regulated by the government - to protect religion from being influenced by the the government. There is NO constitutional basis for preventing religion from informing or being displayed publicly in the government. It always has been.

The goal of the ‘Satanists’ then, to remove religion from government and public life is NOT constitutional and that needs to be pointed out to them
If they argue that it makes them uncomfortable to have religion in the public, tell them politely that there is nothing in the constitution about not having to feel uncomfortable. We all do, but about different things. That is what makes us equal.
Oh, and stop pretending to be a religion if you say that you are not. You are just wasting everybody’s (the public’s) time and making yourself look like silly.
