Do we teach intelligent design and creationism for the sake or morality?

[Smartass]

Creationists argue that teaching evolution has bad practical consequences (not necessarily true that evolution is incorrect).

If a good reason to teach something is for fear of consequences, then :

*Shouldn't we stop teaching history (especially involving slavery, Holocaust, and communism), because it teaches us to be violent?

*Shouldn't we stop teaching gravity, because it teaches us to throw people off airplanes?

*Shouldn't we stop teaching atomic theory, because it teaches us to use nuclear bombs?

*Shouldn't we stop teaching Newton's 3rd law, because it teaches us to use guns to kill people?

*Shouldn't we teach children that Santa Claus and Tooth Fairy are real so they'd behave and become appreciative?

*Shouldn't we teach that liars and murderers will never go to heaven so they'll be so scared they'd never commit crimes?

Isn't ignorance blissful and safe for the future?
