Open-mindedness (warning: long post)

I've been thinking about this quite a lot, mainly because of my brother's blog that I've been reading.  And, based on his blog from yesterday, he has obviously been thinking about it a lot too.  Really, it's a theme that's been coming up a lot lately in my life, and I've been having serious, in-depth conversations about it with various people.   I almost didn't write this blog simply because David had said a lot already, but I think I'll say it anyway.  I have different readers than he does.
