Has One of Your Teachers Ever Tried to Teach You Fake Science?

Science education has always been political. School boards sometimes order teachers to instruct their students that evolution is "just one theory," or to leave sexual reproduction out of health classes. Teachers themselves sometimes insert their pet theories into science classes. Has this happened to you?

Have you ever discovered that one of your teachers was giving you a false or incomplete account of a scientific topic? Was it deliberate, or done out of ignorance? Had they been forced to do it by a school board or was it their choice? Were you able to do anything about it? Tell us your stories.
