The swastika is not a uniquely Nazi symbol.
The Nazis also used numbers, the Roman alphabet, flags, banners, and paper documents.
Should we ban these things, too?
Their swastika was their flag. That they intentionally borrowed the trappings of ancient Rome, as well, and what they otherwise imagined were 'Aryan' symbol, is beside the point, in this case. Yes, the swastika, and those new replacements for it, should clearly be banned. I don't say they should be removed from museums, and studies of the era. I don't say photos should be removed from books reporting on the period. I don't say the films should be destroyed. I'm saying present public display of such hideous notions as represented by that flag should simply not be allowed. So the flag as the physical representation, itself, should not be allowed. If you'll recall, we beat the Nazis. Those of them who faded into the crowd and continued to promote their sect need to come to terms with that. They lost, in the bloodiest war in all of human history, much of it the blood of innocents cruelly executed by those who flew that flag.
