I think you need to supplement your knowledge somewhat to augment what you were taught. It's a big world out there and Old Mrs. Granny Panties might not have told you absolutely everything when you were a boy. This may be a good place to start? I'd follow some links on that page to learn the history of it all too.

Where did I make an ad hominem attack? I was merely pointing out that what they think they know is incorrect. Maybe I should just let them go through life looking like an idiot? It seems to work for you.
