This is nonsense. Many people in the U.S. don't believe in evolution and I don't see any of them burning witches. Stop trying to make outrageous reaches.
Not trying to be mean here, but did you put your stupid hat on today?
The fact is that a certain personality type is the type that will buy into these types of beliefs. The person who buys into the whole no to evolution is willing to overlook mounds of scientific data and hold onto a ridiculous belief.
This type of personality would, if he was born in iraq, would have likely already blown himself up. This type of person also would be the type of person to burn someone for being a witch.
Now I don't know how uneducated and ignorant these people in new guinea are. My guess is they are very. So they have a limited excuse. No doubt a crowd mentality took over there as well.
And no, I am not saying that anyone would burn someone for being a witch here. However, you put someone who has the mental makeup or ability to disbelieve in evolution and rear them in new guinea instead of here, and damn straight, they would be following the group to burn the witch.
