I wonder why you aren't lauding the NSA surveillance program, as it gives you exactly the kind of ammunition to perform such thought police style discrimination.
You will never agree with everyone. The solution is never to "exclude" or "ban" a school of thought, but counteract it with logic and reason. I see no harm in teaching both sides of human origin, it gives children the chance to decide for themselves, and also offers parents a wonderful opportunity to explain their own beliefs while rebutting any they don't agree with.
If a teacher is not teaching evolution perhaps they aren't performing their job correctly, as opposed to being an insidious agent that must be removed due to their crimethink. I hope you can see the difference between job performance and belief systems.
