My response is the opposite: I am surprised that it’s only 10%, and that over 2/3 consider Hamas as terrorist. I suspect the same figures would have described college reaction to the Nazis in 1940, 10% support and 70% strong opposition.
God created man with free will that he can choose between good and evil. Here we can see willful choosing in stark terms. Of course this flies in the face of all people who reject the idea of free will---not realizing their rejection is also an instance of willful choice.
