Spit

"On this date 70 years ago a shell landed in the city of Gdansk in Poland, and then another, and another, and another. By the time the 2nd World War, which truly started that day, was over a third of Poland's population, Jewish and otherwise, was dead, part of the global total approaching 75 million people. So the next time some idiot holds up a sign comparing a politician to Hitler or some blob on the radio invokes the Nazis, remind them of what the real Nazis did, and spit something at them for diminishing the impact and the memory of what really happened by invoking it to inflame people and their petty, trivial political biases."

This is from Keith Olbermann's Tuesday show. Sometimes he comes across as a bit of a blowhard, but this charge is exactly how I feel every time I see someone even hint that they believe Obama is dictatorial.
It turns my stomach to see people cavalierly expressing their displeasure with an amorphous health care bill by painting moustaches on pictures of our president. Hitler and his ego-maniacal attempt to take over the world and murder millions of what he deemed unfit human beings was so evil that any comparison diminishes that horror. And history demands we never do that.
