Here is the basic argument in a nutshell, for those who didn’t read the post below (which you should read, because it really fleshes out the arguments better).
Reynolds compares certain analogies to pro-Nazi arguments, speaks of “policing rhetoric,” and argues for deeming certain viewpoints “unacceptable.”
What Reynolds wants to do with the environmentalists’ claims that “humanity is a virus” is the same as what the left wants to do to our arguments in favor of waterboarding.
Don’t take on the arguments. Don’t debate.
Just slap a label on your opponent’s argument (it’s torture, for God’s sake!!!!) with as much self-righteousness as you can muster. Declare the entire topic beyond the bounds of civilized discussion, work in a Nazi reference if you can, and then — this part is important — stomp off in a huff.
That’s how the leftists “police rhetoric” and deem certain rhetoric “unacceptable.”
Is that how we want to conduct ourselves? Really?
P.S. See Dan Collins for a somewhat contrary perspective.
