So you can show us the solid hole-free roof? Let's see it.
But dude, we have moved on. Our fathers and grandfathers spent their blood and treasure to destroy the Nazis' military power, and exposed the corruption, insanity, and life-wasting futility of the fascist regimes. So today we don't have to pay much attention to Nazis at all, except when we want to use them as villains in movies and video games because no one objects to images and game play depicting their arbitrary slaughter (and sometimes zombies, demons, or killer robots just won't do).
The only thing we still have to worry about with Nazis is people lying and sabotaging the historical record to make them seem okay. "C'mon guys let's have Nazis again." We have to worry about that because there's a danger (however miniscule) of their evil ideology gaining power and then we'd have to go kill them again like our fathers and grandfathers had to do, and that would hardly be moving on, would it?
