The Republican Party and its mainstream supporters are not Nazis. Sure, they have some similarities, but so do we all- to begin with, we all eat and breathe. But the word "Nazi" is used specifically because of its inflammatory value. Because the Nazis were the extreme of the extreme. Comparisons to different forms of fascism can be argued, but when the word "Nazi" is invoked, legitimate argument ends.
Prisoners were shot, against this wall. Thousands of them.
The public is not allowed inside this building. It's where the medical experiments were conducted. Experiments such as forced sterilizations. Experiments on twins to see how one would react to induced, deadly diseases. Experiments of the effects of starvation. Those subjects who weren't killed during the experiments almost always ended up being executed.
The Auschwitz gas chamber.
Auschwitz had been an old barracks, and it wasn't large enough to accommodate the Nazis' purposes. A couple kilometers away, Birkenau was custom-built.
The infamous railroad tracks. This is where arriving prisoners were sorted by Josef Mengele. Some were sent to barracks, to work as slave laborers. Some were chosen for medical experiments. Some were sent immediately to be gassed.
If you were a "lucky" woman, you got sent to live in barracks, such as these. With other women piled on top of you. Freezing, ill, dying. For as long as you could hold out.
Before they left, as the allied armies approached, the Nazis tried to cover their tracks, including by imploding the two gas chambers. Hundreds of thousands of people were murdered in this small building.
Pools of ash, a short walk from the gas chamber.
The teabaggers compare us to Nazis. If we compare Republicans to Nazis, we devolve into a dialogue that amounts to:
You're like the Nazis!
No, you're like the Nazis!
Hitler was writing about gassing Jews in the 1920s. The Nazis didn't devolve, over time. The only valid comparison between the Republicans and the Nazis would begin if the Neo-Nazis took over the Republican Party. They are nowhere close to doing so. That some show up at Republican rallies is no more significant than that some left wing extremists may show up at Democratic rallies. The Republican Party, as bad as it is, is not comparable to the Nazis. It undermines our own credibility to claim otherwise.
