When I first heard of this "volcano censorship" I thought it was a joke. This kind of thing is going too far IMHO. Maybe if they just put a disclaimer in small writing at the end of the film that says:
"This film contains references to natural processes that may involve evolution and large time scales. The viewer is encouraged to decide for themselves whether it is the result of intelligent design or not."
I'm just kidding and I agree with the author that by not showing it we are doing a disservice to the public—those who question evolution and those who do not.
