"Math taught in high schools is pretty laughable" is somewhat subjective but a general observation and evaluation (this is actually easily observable even as an outsider, by looking at SAT Math, AP Math, etc.); "physics isn't even required in many places" is a fact. Neither is a bunch of anecdotes.
My degrees are in mathematics and physics, and I've tutored students in elite colleges, so I know a thing or two.
