You understand that in SCIENCE CLASSES you're supposed to teach SCIENCE, right?
Evolution: A Theory that has been rigorously tested and analyzed over and over. New supporting evidence becomes present every year. Follows the SCIENTIFIC METHOD.
Creationism: In a book written 2000 years ago. Not a theory. Not tested or analyzed. Does NOT follow the scientific method. No new evidence has ever been presented.
Just because you don't have a child in Texas doesn't mean you're not negatively affected by Rick Perry wanting to rewrite science books for Texas schoolchildren.
