If you are refering to mythological witches they come in many forms and as such your question is impossible to answer. Normally though, witchcraft is considered a religion (Wicca) and/or cult while humans are a race. In this example your question isn't just impossible to answer but is actually impossible to ask.It would be like asking what a half christian, half human is called.
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.
