They aren't morons.

They are mislead.

Perhaps, but I'd be mislead too if someone said to me "Hey moron, you don't read the Bible. Let me teach you how you're wrong." You can be ignorant of something and not be a moron, and in many (not all, but many) cases its smart not to listen to destructive feedback. My only point being is that if one is going to educate someone in some way, do so first by example and again through respectful communication.
