I know it's true, but i find it hard to understand how, with all the scientific information available, that the anti-evolution movement in the US is strong and growing.

Not only is it growing, Evolutionists are converting to Intelligent Design proponents. This is based on the scientific evidence, not materialist philosophy.
I love the fact you "KNOW" evolution to be true eg. There are many much smarter than you that aren't so sure. You are mighty confident in your knowledge. The scientific evolutionists are, as we speak, struggling to confront the scientific basis of the ID movement. They have not done so.
I wonder if the "clipsize portion" is not due to some attention deficit disorder.
