They have their wish. The theory of evolution is taught in every public school, whether the parents (who pay for it), teachers (who actually do it) or children (who are forced to learn it.)
In fact the victory of evolutionary theory in our public schools has been so complete that I wonder why they even see the need for such a petition. I can only conclude that at last the left feels the reigns of power loosening from their grasp, ever so slightly, and they don't like it.
Exactly so, and has been (almost universally) for several generations. If Darwinism is the key to education, why don't we have the best-educated public-school students in the world by now?
