To claim faith undermining, the survey needed to be restricted to practicing [or at least self-declared] faithful, for otherwise it is meaningless. How could a film/book [or anything or anybody, in general] undermine the faith in one who has none?
Good point. Others may disagree.
My thoughts exactly.
I read that sorry excuse for a book and want my 5 or 6 hours back. But my faith is still intact.
