A real satanist would applaud people “doing what thou wilt”. That’s the first commandment of the satanist: do what you want. Right there in LeVay’s Satanic Bible, Aleister Crowley approved.
Obviously a couple people wanted to take these folks’ poster. They did what they wanted. They are living the satanists’ faith better than they are.
I now have to question the sincerity of their satanic faith.
And the Satanists are now doing what they will, which is pretty pathetic, but still it’s what they will: complain!
