McGrath: I agree torture is an unmitigated evil. I agree that if Americans use it, they are doing wrong. I agree they are probably using it, so those persons or groups of Americans who are problably using torture are probably guilty of serious misfeasance. If they are torturing people, or authorizing torture, they should be made to stop. And punished.

But they are not "terrorists." Not all bad things are identical to all other bad things. You are using a metaphor, as if the only real meaning of a word were its metaphorical meaning. Thats a debating tactic; should not be used in a discussion where people are actually trying to persuade, rather than merely score poings.
