I believe Satan is at the heart of most pagan religions, using magik you call upon demons, take Wicca for example it is based around calling upon spirits to preform magik, the origins of Wicca lead to Gardener and Alistair Crowley (famous statanist) watch the below video to learn about Alistair Crowley (Wicca is the work of Satan)
I think this post answers the OP's question rather well (if inadvertedly so).
It's also brimming with (cultivated) ignorance.
1. Aleister Crowley, while most certainly a controversial figure who did his best to shock and offend Christians and polite society alike, was not a Satanist. In fact, he had some very strong words for the so-called "Black Brothers", regarding them as fools who'd get stuck because they cling to their ego-constructs, never attaining mystical union. And contemporary Satanists (theistic or non-theistic), in turn, tend to regard him as a "right-hand-path"-representative, more akin to Christians than to themselves.
2. Gerald Gardner certainly "borrowed" from Crowley (and from the Freemasons, and from BDSM subculture, and from Margaret Murray's "Witch Cult in Western Europe", just to mention a few). But Gardnerian Wicca is still pretty much an entity of its own, and has got nothing to do with Satan at all.
3. Wicca - while certainly the most well-known and widespread manifestation of neo-paganism - is not at all synonymous with (neo-)paganism. There's lots and lots of different approaches, from neo-shamans over reconstructionists of the various ancient pantheons (Egyptian, Greek, Norse), to the syncretic religions of the Caribbean and South America, combining traditional African religion with local customs and even some Christian influences. What's more, there are about a gazillion people out there who call themselves "Wiccans" even though their ideas, beliefs, and practices have got virtually nothing to do with Gardner.
4. At the end of the day, what neo-pagans call "magic" is usually not that different from what Christians call "prayer" or "mass": there may be a
theological difference between the two, yet in terms of
practice, a Dianic Wiccan invoking the goddess is not all that different from a Catholic priest performing the transsubstantiation, or a protestant speaking in tongues.
