If you read the testimony of the woman who grew up in The Church of Satan (which is hiding inside the LDS churh in Utah, you will get a better idea of what this evil is. The documents were posted here multiple times over the last couple of days. I think they hide in the Catholic Church and other religions as well, because the CS is mocking God and his natural order.
The information in the testimony documents synthesizes a lot of the disparate things we have learned and will change the way you look at EVERYTHING.
