Well, even though modern-day Satanism is really more of a philosophy than a religion (for instance, Satanists don't "worship" Satan, they emulate the rebellious archtype which is called "Satan"), I would still describe it as being neopagan. That's if you define the word "pagan" as being "an irreligious person". Of course, the original definition of "pagan" was as you described above -- and also a person belonging to a community professing a polytheistic religion.
They've got you reading Pope Innocent VIII? "Thank the spirits of whatever that we don't live back then. (Ugh.)" Phyllis, we're not *that* far removed from the mentality of those times. Not when, within this past year, the current Pope decides to make a "saint" out of Pope Pius IX -- the Pope who condoned the kidnapping of a Jewish child as recently as 150 years ago in order to "save the soul" of that child and give him a "better life" being raised as a Christian. Little 6-year-old Edgardo Mortaro was the Elian Gonzales of his time -- but, unlike Elian, Edgardo was never returned to his father.
Ask your instructor to cover that topic in class sometime. It's not that far removed in history, and it can be directly compared to the arrogance -- both religious and political -- which one sees all around us even today.
