Actually, I said most. The 30 to 40 percent of teachers who won't send their kids to public school are the smart minority.
How do you define "dimwit"? (You used the word first to describe some homeschoolers) I would define "dimwit" as someone who ranks near the bottom of the class. (see post 218)
From that same link: "...the Philadelphia Inquirer reports that in Philadelphia, “half of the district’s 690 middle school teachers who took exams in math, English, social studies and science in September and November failed.” Notice: half of the currently-certified teachers failed the relatively easy state teaching test but are still teaching in the classroom!"
A dimwit is someone who continually makes the same dense mistake; a dimwit doesn’t value knowledge to the extent he does not pursue it. A dimwit, for example, wouldn’t even bother taking the SATS or aspire to go to college or law school. A dimwit is often oblivious to his or her dimwittedness. Literally, a dim wit.
