Oh, probably some clap-trap like "Love thy neighbor as thyself" or "It is better to listen than to speak." Depends on my mood and which face of your immobile and towering "position" I choose to scale tomorrow. I do find it interesting that I said, "As many (would be janitors) as want to be." and yet you heard something about exalting the power of the meek. Interesting. What kind of work do you do, Carl? And how is _your_ workplace hierarchy structured?

Remeber, as I said, mine are only "stances" and tomorrow another may serve my purposes much better than the one I present today. So, please, don't let your assumptions get in the way of seeing that.

In a group of people using religion as a blinder to keep them from understanding rationality, my stances might be just the opposite of the ones this situation calls for.

A great article (I've included it again below). I'm glad you could use my completely unrelated comment as a segue (sp?) to it.
