From Robinson's March 30 Washington Post column:

The episode highlights the obvious: For decades now, the most serious threat of domestic terrorism has come from the growing ranks of paranoid, anti-government hate groups that draw their inspiration, vocabulary and anger from the far right.

It is disingenuous for mainstream purveyors of incendiary far-right rhetoric to dismiss groups such as the Hutaree by saying that there are “crazies on both sides.” This simply is not true.

[...]

It is dishonest for right-wing commentators to insist on an equivalence that does not exist. The danger of political violence in this country comes overwhelmingly from one direction -- the right, not the left. The vitriolic, anti-government hate speech that is spewed on talk radio every day -- and, quite regularly, at Tea Party rallies -- is calibrated not to inform but to incite.

Demagogues scream at people that their government is illegitimate, that their country has been “taken away,” that their elected officials are “traitors” and that their freedom is at risk. They have a right to free speech, which I will always defend. But they shouldn't be surprised if some listeners take them literally.
