If you want to persuade anyone, making any of these sorts of arguments will get you nowhere. I've seen some pretty persuasive arguments on the against side recently, even if they're misguided or just plain wrong.
All the for arguments I've seen are still begging the question and just throwing slams like this one, and even a recent video scientists made just keeps saying the science in irrefutable, which does nothing to persuade anyone.
But Kerry is right, the better deal, in Trump's mind is probably just not doing it.
