When I was a child my Father, who was a fundamentalist, warned us about the occult. Anything from dark imagery around Halloween to episodes of Scooby Doo were considered dangerous and seen as contrary to God.
I can remember seeing some older kids on my street playing with Magic the Gathering cards and being warned to stay away from them as they might let very real demonic entities in. As a kid I had received some Pokemon cards as a gift from a friend only to have them confiscated by my Father for having a kind of Pokemon that were "PSYCHIC" and thus tied to the occult and the Devil.
There are verses in the Bible which compel people to stone witches and mediums who speak to the dead.
So to sum up yes, to some (usually fundamentalist) Christians the use of Magic is seen as evil or tied to the Devil. While today the religious cannot get away with torturing or executing those who practice these arts there are still those superstitious enough to see practitioners of Magic as evil.
