Perhaps the “teach all sides” argument appeals to the American sense of fair play, but to an educator it’s truly disheartening.
If an evolutionist were truly being honest, they would say that even though they believe their evidence to be convincing, it isn't conclusive and therefore other theories that have at least some evidence and haven't been proven false should also be taught. Why not? When talking about the origin of life and the universe, we can never know for sure - what's wrong with teaching several theories? Unless you are simply scared that yours will be discredited and pales in comparison to your competition.
