science teacher not allowed to teach science

Arkansas public school science teacher says faculty are forbidden to use the “e-word” (evolution). More: “I am instructed NOT to use hard numbers when telling kids how old rocks are. I am supposed to say that these rocks are VERY VERY OLD…but I am NOT to say that these rocks are thought to be about 300 million years old.”

This is just absurd!
What's next? Not being able to teach that 2+2=4 in fear that it will offend someone?
