Based on this and the reest of the subthread, while I can't upvote the initial comment, I'm just pointing out that I've upvoted the entire subthread because we should encourage such discussions - especially ones that don't devolve into personal attacks and arguments. This subthread discussed the issue and pretty much cleared things up. While I knew basically all of this in this instance, with these types of discussions, I often learn things that are good to know.

So I encourage folks to see this as a positive, and encourage it. :)
