With the ratcheted up vitriolic rhetoric the Left has been spewing ever since the tragedy last Saturday in Arizona, you might think they would just fade into the background out of sheer exhaustion. But the lies keep on coming, and they have a new line about violence not being part of political discourse. What is political discourse? Who defines it? The Left?

People like Sheriff Dupnik of Pima County and Janet Napolitano desire to silence the opposition, whoever we may be. Theirs is an attack on free speech-of conservatives.

Sheriff Dupnik in HuffPo:

Pima County Sheriff Clarence Dupnik has found himself at the epicenter of the post-Tucson political debate after implying that some responsibility for the shooting of Rep. Gabbie Giffords and 19 others was with the state of discourse in the country.

There is no place in our society or discourse for such senseless and unconscionable acts of violence. Gabby is a steadfast representative for southern Arizona and both she and John [Roll] are dedicated public servants.

I have seen firsthand the effects of assassination, and there is no place for this kind of violence in our political discourse. It must be universally condemned. We do not yet know the gunman's motivations, but I am convinced that we must reject extremism and violent rhetoric.

The extremists and their voices, the crazy voices that sometimes get on the TV, that's not who we are, that's not who you are, and what we have to do is get through that and make it clear that that doesn't represent either American or Arab ideas or opinions.
