Thanks!

[These questions used to offend Anita, but now she finds them kind of amusing. People are just curious, after all.]

None taken. The answer is yes and no: there are people called bokor, a small subset of vodouists who tend to use their powers for evil. But they're not the norm, and I'm not one of them, so you can count on me not to make a loa doll for you or turn you into a zombie or something.
