Just a comment on the thread itself, not on the subject of the thread: even when the discussion heats up and MR members resort to shouting at each other (so to speak), it is more endearing than disturbing. I avoid most other internet sites because participants suck all the hope for humanity from my soul.
Kudos to everyone who vigorously and passionately defends his/her position while trying to demolish other arguments and all while refraining from nastiness and personal attacks. (A short descent into shouting is oh so human, but not nasty).
Carry on.
