For what it's worth, I didn't read any "scorched earth" rhetoric in dougmwme's original post. I thought it was a reasoned argument, well-explained, in a way that gave me a really interesting perspective on the situation (as someone who has heard and thought about these sorts of perspectives often).

Maybe read it after applying the principle of charity, without assuming the writer is angrily banging on the keyboard, and instead is being thoughtful and trying to teach?
