Ah, Kissimee, I just tell myself that some folks simply don't know differently in general and they don't know better in particular. If someone's point of view is emotional, there is no possibility of a rational discussion, those feelings keep getting in the way. Any questioning is perceived as a personal affront and an insult, and the personal attacks are the result. And the preaching goes with the territory too if you think about it. It's just the nature of it.
So, what else would you like to talk about?
