That exchange between @lukestokes and @sircork brought out the best in both of them, I think. If not the best, at least the unvarnished truth. I was awed and humbled by that conversation, not only because of how technically in-depth it was, but because of the humanity I saw in both of them. I know readers of this comment may think this is my attempt to tiptoe around having to say they argued. No, I promise you it isn't. What I saw was not an argument. It was a true meeting of the minds, where both made points the other couldn't (and didn't) ignore. It was a beautiful thing to see. And then Amelia's contribution--she was able to articulate everything we'd all been trying to say about a certain issue, and put it in a way that made sense for the first time.
