Before you know it they are laying siege to the walls of Jericho and then storming in to kill with the sword “every living thing in it—men and women, young and old, cattle, sheep and donkeys”. Or, perhaps forming themselves into armies and crusading across the land slaughtering everything in their path. Or perhaps they are hijacking planes full of people and flying them into buildings full of people.
They deny the existence of the devil within themselves and so they have no awareness or control over it when it comes to the surface and starts on a rampage of evil. When their own darkness surfaces to take over their minds, they fail to recognize it as such, and every dark thought they think begins to appear as light, and every dark impulse of their own will becomes contorted to look like the will of God. Driven by their own disowned evil within, they set out to hunt down and destroy an imagined evil enemy out there. They are driven by a need to find one and always seem to manage to do so. And so once again the world burns as they go off to battle, killing person after person, and never understanding why they can’t ever seem to win their war. It’s the “devil” they say, he is strong, but we have God on our side, we will defeat him in the end if we don’t give up.

“Look, over there, I think I see one of his demons now. It is trying to hide as something innocent. I am not fooled. I know evil when I see it. I will go and slay it in the name of the Lord. Take that demon! Praise be to God, Allah Akbar, and all that Jazz.”

Just another day in the army of the righteous. A bunch of nuts dancing or chanting around a fire, be it a bonfire or a single candle, may not seem frightening, but put it into the context of the history of the human race, and there is plenty of genuine evil there to be absolutely afraid of.

You just described religion in general. But theistic satanism is imho too small to count as an official religion but rather they are cults composed of outcast losers that have nothing better to do with their time. So I don't see any threat in them, except for their mental state.
