I don't feel like getting into this debate right now, but I want to apologise for the tone and unwarranted brevity/sweepingness of my first comment. The comment I was responding to upset me and I responded more from upset than from thinking about the best way to make my point. I should have argued my point carefully and calmly or refrained from making it at all. I'm going to go with the latter in this thread, but I wanted to say sorry!
