Isn't it funny how they don't even realize that they're saying whites are smarter than blacks with this outcry?
Algebra uses practically no Greek letters. Geometry uses only a few (sometimes using two or three Greek letters for designating angles, but more often using our Roman alphabet for labeling those angles). Trigonometry uses a few Greek letters, usually only three or four, as I recall. Is the teacher saying that black folks as a group can't handle even a few Greek letters? And why hasn't she plausibly explained why white kids (seemingly?)
can handle a few Greek letters? This is a truly embarrassing theory on her part.
Calculus, of course, uses a lot of Greek letters (especially in spherical calculus), and physics uses even more. Black folks who make it that far might find these subjects difficult--but most white kids do, too. It has nothing to do with the use of Greek letters.
The math teacher in the article ought to be fired for being a race-baiting idiot. And as I have already suggested, the liberals ought to lead in that charge against her--since
everything in her theory backfires against them.
