School is not the place for political protests of any sort. School is only a place to learn the material presented.
Oh puhleeeeze....
For some people, if you don't teach your particular sect's teachings, it's "secular humanism."
There's a huge difference between teaching from a secular, non-sectarian viewpoint and teaching secular humanism. I was never taught in school that there is no God, that empiricism is the only valid epistemology, or that religion was the opiate of the masses. I was taught history, science, and literature. The chips fell where they may.
Are you serious?! What material? Presented by whom?
What do you mean by learning? Memorizing?
