Another thing that occurs to me is that, the Lord keeps his angels about us, to help lead, protect etc... and if you start getting involved in things that attract adversary spirits, that could cause a number of issues... they need to somehow cause you to do or say things that make the Lord's angel go away. Basically, sitting on the fence is not a good place to be.

I've heard a good number of stories from people who were once involved with witchcraft who were told by familiar (unclean) spirits about (Christian) people they couldn't get next to because of angels in the way. The spirits do see the angels.
