Humans are not descendants of monkeys, everyone knows that. Evolution teaches that humans are descendants of pond scum. OK, maybe "pond scum" is not P.C. enough for you, but it's relatively true, based in evolution.
As a former public school student I must agree. Evolution is taught and an other idea is viciously destroyed. Trust me, I had lots of fun in biology when the teacher would bring up evolution and then I said, "What about other possibilities?" and she would look at me and say, "There is no other possibility, this is the answer."
When I took AP Bio I had a diff. teacher (diff. school and diff. town) and I got nearly the same answer. My AP Chem teacher was an ex-atheist and new-born Christian who had actually come over because of the errors he say in what had been taught to him by evolution and such. (He also taught Bio) He visits one of our Christian Student meetings and shared with us how evolution was unsettling and full of fallacies. He also said that the head of the science department (for my high school) said that teachers should disregard any comments against evolution saying anything else was a "waste of time".
