You clearly have not taught mathematics at either the college level or the high school level. But your experience carries a great deal of weight. You are correct. I’ve taught mathematics at Purdue University, Florida State University, University of Kansas, various community colleges and in a prison. I don’t know what I’m talking about. The book in question should be a course at every high school. Each high school will certainly have enough students who can take such a course to justify having the course.

By the way, don’t look up what an outlier is and don’t forget that your anecdote is, in fact, data.

Indeed, I have not. Nor do I need to in order to make simple observations that contradict your claims. You are representing that something which is already widely put into practice is infeasible. A strange hill to die on.

The amusing thing is that if your claims weren't framed as an absolute they'd likely be correct. But when you attempt to make sweeping generalizations about the entire country you will almost invariably be wrong regardless of the topic at hand.

I'll also note that intentionally misattributing claims to me is neither in good faith nor in keeping with HN guidelines.
