White vs. Black Magick
It's a rather controversial issue, with several sides. The first thing you have to do is decide whether there IS a difference.
Some people are of the position that there is no difference, and not all of them are Bible carrying Christians!! Some of them are practitioners of magick! One of which is Silver RavenWolf. Here's why.
Magick itself is neither good nor evil, but something which connects the two. People who are 'good' and people who are 'evil' can both use magick. Most of the same 'spells' will work. It's not what magick is, but what it is used for.
