Probally what these folks are saying is this. That where they see certain practices, they also notice a moral decline and acceptance of behavior that would be condemned in areas of other society. - - - Here in New Orleans there are quite a few black magic shops in the French Quarter and around town, you will commonly notice there is the existence of other social ills right within the vacinity or either right next to an area where black magic is performed. Strip clubs, heroin and acid shops, 25cent sex act booths, etc. But where there are Churches, there tend to be no such things. As bad as drugs are here, not even the roughest of dealers will sell near a church nor will a topless bar owner attempt to build a club next to a church or Mosque but the lowwest of human behavior often goes on where there is belief in the occult. I've studied nearly every religion and belief system on Earth and many are tolerant of things other condone. But it is true about some Christians, some enter with ill intention in areas where they have interest.
You need to read some of the other links. Some of these "preachers" are profiteering from phony exorcisms.
Which is the worst form of "black magic"!
