Number 1 - Peaceful people - a lot of these people were were terrorists that were intent on destroying the US.
Number 2 - Auschwitz - either one you don't acknowledge the holocaust or you are trying to piss off a lot of people. We do not gas and kill people at GITMO. The people that are there are allowed to pray, we feed them culturally specific food, and have proper healthcare. Most have gained weight since being there - No comparison.
Number 3 - The Geneva conventions only apply to signatory nations - Afghanistan, Pakistan, Iran, Iraq and others are not signatories.
Your statement at best is intellectual dishonesty, at worst a flat lie.
