And if you want to learn baseball, you go to your baseball coach, who may very well be a doctor or a preacher as well.
You strongly implied this in your first post.
A question for you or anyone else here:
I'm an atheist, a skeptic, an ardent secularist, and an engineer. I also volunteer at an elementary school, where I'm a mentor on the school's robotics team. IOW, I'm involved with teaching kids, though only for an hour a week and not in a traditional classroom setting. I don't talk about religion with the kids... though I do happen to think that the methodology we use in the robotics club* encourages skepticism.
Given all that, do you think my atheism or my active involvement in the secular movement makes me unfit to help in a school?
*For the most part, the kids have to build autonomous robots to perform specific tasks or "missions". This means they have to come up with a hypothesis of what should work, translate this into a methodology (i.e. a robot design and a program), confirm the hypothesis through real-world testing, and rationally examine the process if the results aren't what they expect... IOW, they have to employ the scientific method (or, if you prefer, take a skeptical approach to problem-solving), though I think the kids generally just think of it as "playing with robots".
