Actually, this is kind of funny.
Biology teachers in most areas are prohibited from teaching anything other than evolution. It is your side that is imposing restrictions on how they do their job.
False. In every single case, it was SCHOOL BOARDS and STATE LEGISLATURES who were attempting to FORCE biology teachers to either undermine evolution or talk about intelligent design.
In Dover, PA, where the latest case was fought, the school board instructed the teachers to read a statement before class about intelligent design. The teachers, all of them, REFUSED.
