If you went to a neurosurgeon, to operate on your brain, you would ask about his credentials and past experience, wouldn't you?
So why if I am going to trust a generation of children to living in this world, not check what people in this world believe? What their past is?
If you are not going to tell me why you believe what you believe, why would I leave my children in a vulnerable position - where they can't trust what is said to them?
Scientifically, I have an obligation to investigate the motivation you have for what you believe - as pertains to the Evolution I pass on: if you are not invested in that, why do you bother to learn Evolution at all? Do you want me to come up with a reason, or is your taste invested in bringing down people that don't believe what you do?
