Perry: You know what's despicable... hanging the bodies of our contractors off bridges.
So, hanging bodies bad, urinating on them not so bad.
He said it was not good and should be punished.. are ewe deef?
I don't have the transcript in front of me, but I understood him to be listing things that were worse than Marines urinating on corpses (which he called "a mistake"). Hence, "bad" and "not so bad".
And as far as cutting off people's heads, I agree with Perry that this is generally worse than desecrating corpses. Even in a GOP debate, it's not worth listing all of the things on which I agree with speakers.
