"Umm, what was that Abu Ghraib scandal all about? It started out as misconduct between men and women and then it steadily deteriorated into abuse of prisoners. The common denominator is lack of discipline. Once you break down discipline, good order and discipline and morale, everything that’s required for unit cohesion, you undermine the culture and the strength of the armed forces," - Elaine Donnelly, in an "argument" against gays in the military.
At this point, you realize that they really do live in an alternate reality, immune to evidence, hostile to reason. The Abu Ghraib scandal was about the torture and abuse techniques authorized by Bush and Cheney and supported by the vast majority of Republicans actually being photographed and documented. It was an example of what happens when a president unleashes torture in wartime as a legitimate tool. That it could be used to argue against allowing many servicemembers to serve their country without being persecuted for it is simply gob-smacking.
