The point is the principle. The money amount is not the point because if it’s a sold-out event, the ticket sellers make the same amount no matter who are the buyers. The principle is that the money shouldn’t come from non-satanists, who should steer clear of any connection to such an event.

It’s like if a person decides to protest income tax so that he doesn’t enable government evil. The protester realizes the government will continue to do evil without his support until there are enough protesters to shut it all down. In the meantime, his conscience is clean that none of his labor or life force was redirected to wickedness.
