Anxiety over the speech seems particularly high in Texas, where many districts are offering parents involved in the boycott movement the option of taking their children out of class. (Whoever thought we’d see Texas treat advocacy of personal responsibility like sex education?)…

That paranoid fantasy is what’s really behind the “birther” movement and the allegations that the president is — take your pick — a secret Marxist or a secret Muslim.

It’s the kind of fanciful anxiety that produces comments like this, posted on a conservative website this week: “Barack Obama and his left-wing Chicago machine regime are putting into place laws and institutions which will insure that there will never again be free elections in America.”

These are the people who are stockpiling ammunition and keeping their children at home next Tuesday.
