You would think that where they are invoked to make a point, it would be done with a respect for the incalculable evil the Nazis represent. You would think people would tread carefully, not because of the potential insult to a given politician (they are big boys and girls) but because to do otherwise profanes the profound and renders trivial that which ought to be held sacred by anyone who regards himself as a truly human being.
But in modern America, unfortunately, rhetoric often starts over the top and goes up from there. So fine, George W. Bush is "a smirking chimp." Fine, Barack Obama is "a Chicago thug." We have a Constitution, after all, and it says we can say whatever we want. It doesn't say that it has to be intelligent.
And yes, you are even protected if you liken Obama or Bush to Hitler.
