I am deeply unhappy with western math curricula. Teaching integrals before derivatives. Teaching trigonometry without the unit circle. Teaching integration without riemann sums. Teaching probability without it's axiomatic definition. Teaching calculus before basic stuff which isn't calculus. People have an unhealthy obsession with calculus - wow! derivatives, wow! integrals - and then you see a clueless person who sees a quadratic-related problem and can't solve it but they can give you an indefinite integral of x^2 or tell you what a conjugate of a given complex number is equal to.
