Unfortunately, the reason that evolution is not taught to any degree in required biology classes is due to intimidation. Biology teachers feel threatened by the student body, the parents of the students, and by the school board. Some teachers will not teach evolution even if it is required by the state guidelines for curriculum. Teachers have reported recieving anonymous copies of creationist propoganda on their desks, threatening letters in the mail, and even insults from students during class. What the creationists can't get through science they are now getting through political and social mechanisms. States, school boards, and individual teachers are sacrificing education for better treatments from the public. It is a shame, but a reality nonetheless. Many science teachers are now asking "Why doesn't someone ask the History teacher if he believes in God? Why am I being singled out?"
What I tell many creationists is that you are only required to learn what the theory of evolution says. You are not required to accept it. That, and how are you going to prove evolution wrong if you don't even know what evolution says.
