Michelle Malkin has a wonderfully effective way of being quite direct. Consider this posting entitled Shut Up and Teach:

The National Education Association recently had its annual convention, where it called for President Bush to withdraw our troops from Iraq, vowed to defeat the Central American Free Trade Agreement, and resolved to educate about the need for debt cancellation in underdeveloped countries.
And you wonder why Johnny can’t read.

A left-wing political agenda that has nothing to do with educating our children well. That insists on no changes to their rich pension benefits while insisting there be no competitive alternatives for educating our children.
And to think we have given them the unilateral right to legally extort communities across America so we then have to overpay for their underperformance.
Wonderful, isn’t it?
