After last week's Arizona shootings PBS News Hour asked if it might be time for U.S. politicians and media commentators to tone down the rhetoric.

Then yesterday that gyro-eyed merchant of idiocy Sarah Palin issued this:

“If you don’t like a person’s vision for the country, you’re free to debate that vision. … But, especially within hours of a tragedy unfolding, journalists and pundits should not manufacture a blood libel that serves only to incite the very hatred and violence they purport to condemn. That is reprehensible."

Leading the Globe and Mail's Margaret Wente to write:

"If America were a person, it would be a 14-year-old girl."

Where is this headed?
