And there's a particularly bad habit on the part of Republicans trying to downplay or sympathize with extreme-right violence. Scott Brown offers a perfect example in his remarks yesterday:
"I don't know if it's related but I can just sense not only in my election, but since being here in Washington, people are frustrated. They want transparency. They want their elected officials to be accountable and open and talk about the things affecting their daily lives. So I am not sure if there is a connection, I certainly hope not, but we need to do things better."
There's no excuse for rationalizing domestic terrorism. This is a much greater problem in America than the threat of foreign terror attacks; our own history has born this out. It's not "terrorism" only when brown-skinned people do it.
