People's actions are based on what they believe. Your beliefs basically make the decision for your actions.
Deep in their heart, belief systems motivate their motions, that is, their actions.
Their motions are motivated by the motor of their heart felt beliefs.
The actions you take in raising your child, selecting the school, making the menu, all those and more are decided by what you know and believe.
The basis of your thoughts will determine what you do.
The foundational principles of your beliefs will be the deciding factor in your actions.
The Supreme Court has published their conclusion that the definition of religion is that set of beliefs that determines what a person does.

If you're a traditional American, do you want a new-world-order teacher for your children?
If you're a Christian, do you want a Satanist teaching your children? No, because the tone of what they teach is colored by what they believe. Clear and simple, it applies to every subject.
