You know I thought that this a$$hole didn't know about things like the Warsaw Ghetto, but upon reflection, I think he does know about it.
He just doesn't view it the same way we do - as the the evil Nazis crushing the resistance of the heroic jews. In his viewpoint, the Nazis were the good guys. They were the lawful government, and the jews were criminals resisting lawful authority. The only losses this guy would regret in his modern day gun owner as jew scenario would be losses to their beloved police.
And I think that there would be considerable losses. Gun owners would just cower in their homes waiting for the door to get kicked down. I think all sorts of ambushes and ieds would start cropping up. And the score settling that he mentions in his piece of filth editorial? I think there are people in his area who would settle his. So the jerk better pray that his nazi dream of America doesn't come true, and he can continue to vent his fear and hatred of freedom from his nice comfortable position.
