For the most part I enjoyed the "Satanic Scriptures", Though I do feel much of his written work leaves much to be desired(the topic matter kept me going)...I can't take issue with him as the leader of the CoS because I'm not a member and they are quit mum about their actions (or inactions as they were).
I've never had a CoS card nor do I currently desire one this is because I feel that Gilmor and company seem to think or at least imply that they have ownership over the term Satanism. For example the article written by Gilmor titled "Rebels Without Cause" that can be found on the CoS web site seems to suggest this. Though I agree with some of what he says here may point and one of my reasonings for not wasting $200 for a little red card that probably costs less then a fourth of the current rate to make and send and also LaVey charged half the current rate prior to his untimely death is that seem to at least imply that the CoS owns Satanism and it's philosophy.
