KKK. Holocaust. Racism. Hitler. These words are thrown around as a comparison to people and events that are happening in today's society. All these words have an impact all by themselves but are becoming trivial by people that use these words so loosely.
Hitler was a monster. He was evil personified. As much as we may dislike (being very generous here) politicians, to compare them to Hitler is undignified. I've seen many signs comparing both Bush and Obama to him. If you think that our politicians resemble a man that was capable of atrocious, heinous acts of mass murder then you really need to go back and do some research.
