I'm a big fan - to the point of having made/spammed a prospective bumper sticker for a '16 run on here for months - but on this issue you're either just plain wrong or being purposely obtuse, imho.
If it would have prevented 9/11, I'd have waterboarded (etc) a thousand of the evil savages with a clear conscience.
Beware the slippery slope of PC appeasement, lest the low viscosity of its rationalization impel an incremental slide into GOPussy irrelevance.
In contraposition to Voltaire: a perfunctory 'good' is often the enemy of the best.
It may not be much in the world of bumper stickers, but I sure hope not to have cause to regret it . . .
I guess the question is, Is waterboarding torture?
