Michelle Malkin posted an interesting piece over the long weekend about an English teacher in Vermont who repeatedly made pro-liberal, anti-conservative statements during vocabulary exercises.
A sample question which asks the students to choose between the words "coherent" and "eschewed": "I wish Bush would be (coherent, eschewed) for once during a speech, but there are theories that his everyday diction charms the below-average mind, hence insuring him Republican votes."
The original Boston Globe article is here. The headline, which says the teacher is under investigation for "alleged liberalism," is misleading; obviously, no one has a problem with a teacher's right to be liberal, the problem is when the teacher uses his classroom as a bully pulpit.
I wish I could say this kind of classroom indoctrination is unusual, but I know from firsthand experience that it's not.
