They may have treated the German and Japanese POWs better but they STILL HAD PRISON CAMPS.
In the violent conflict between communism and the rest of the civilized world (as with Islam,) you can choose to hold to a higher standard only so long as your survival isn't at stake.
If there were bombs going off on buses and in malls all over every day, how long do you think it would take for us to set up internment camps and then begin mass deportations? It sounds like your logic would have us pretend that there isn't a problem in a society at war.
It's like saying that if I KNOW there's a guy who is raping kids and getting away with it, that I'm wrong for killing him without trial. Republican government is only so strong as the institutions and obedience to its values held by the vast majority of the people. Otherwise it's merely a vehicle for a scumbag like Hitler to take power and then begin mass genocide and wars of conquest.
I have no problem saying that. You would indeed be wrong for playing judge, jury and executioner. There are reasons we have due process. Up until recently, I thought this was a concept that would have been easily grasped, but I'm learning that it's not the case.
