Voodoo - If someone that hates me put my hat on their alter what are they trying to do?

Since voodoo isnt real it hardly matters what they are trying to do. The only people who believe it works are superstitious people and religious and cult fanatics. Ignore and go on with your life and dont play their stupid games.

There is no such thing as black magic. It’s purely up to the person choosing to believe they have been “cursed” and then behaving in a self-fulfilling prophecy sort of behaviour to “prove” they were cursed.
