The fact that you believe that a Wiccan can harm you is what makes you vulnerable to that kind of harm. These things only operate by suggestion. This person doesn't have to do a damn thing.
This person doesn't even need to exist. I could call you up tomorrow, and say "Hey insert name this is Anne, from Yahoo answers. Somebody told me that Jane who lives on Main street is going to put a curse on you.
She saw you at McDonalds with your friend Bob on Thursday, and pulled one of your hairs off of your parka." You would freak out, without any proof that Jane even exists. I could have some kind of knowledge that you and Bob were at McDonalds on Thursday, and exploit you.
This is how these things work. The only Magick is in our minds. Our minds can bend spoons, but there is no "spell" that works without the human psyche.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
