I'm pretty pleased with the way this is going. Lots of good, thoughtful comments, which is what I wanted to see. As I said in the beginning, GUEST,pdq, I was a bit apprehensive that it might be divisive, and it certainly has the potential to be, but I wasn't trolling as your posts seem to imply. I think this is an issue (actually a combination of issues) that people should be aware of and should think about seriously. And it looks like they are. Excellent!
