At this point there's really no difference between your average leftist and a satanist in terms of their values.
The kinds of defective people who parade around as satanists are just attention seeking losers, into bad metal music, clothes, and all around sleaziness.
I agree with your assessment of these “Satanists.” Immature, narcissists, wanting attention from the media. The hardcore Satanists do not advertise themselves or stick out in any way. They’re master infiltrators. Nonetheless, to spend tax payers’ money on such a spectacle is evil. It’s robbing the workers of their pay, a sin against justice as well as mocking God.
IMHO, the best way to deal with this sort of thing is to do everything possible to make it a huge nothing burger, a flop. Let the city and state lose money on it and the people who show up those those looking for freebies, can’t afford the souvenirs and food court, won’t be invited back, will fade swiftly from the public’s memory.
