I think Bill Clinton has a point about the effect of language of people's behavior, and it is important when tough issues are being discussed to avoid language that could incite and inflame people to violence. The unfortunate problem with the point he made is the implication it is only parties on the right that have been violent, and that we need to be concerned about. Truth is, there are people on all sides with the ability and the willingness to be violent. Truth is language on all sides goes too far.
