One difference is that back in 30s Germany you probably didn't have a bunch of Starbucks-sipping, Bloomberg-following, wussy-acting, liberal-media-believing, pansy-resembling, wingnut MOONBATS hanging out at the day spas in Cambridge, Brookline, Newton etc etc etc, telling each other (and, importantly, their CHILDREN) that the Naziis were doing the right thing...."because, little son or daughter, the Nazi's are GOOD, and GUNS ARE SOOOOOOO BAD!!!!!!"
That's one difference I see anyways.
Hell, some of these idiot pus*ies probably think reincarnated Nazis would be a good thing, if it would just make those mean, nasty, ugly, noisy, scary GUNS just vanish from the earth. And, for that matter, they'd vote Obama a 3rd term, if there wasn't a constitutional provision against the Kenyan-in-Chief running again.
Just walk around Boston, Brookline, or ride the MBTA green line, etc etc and listen to the conversations these liberal sons and grandsons of Dukakis voters are having. Just listen to how incredibly BRAINWASHED they have become.
