I don't care about my doctor's opinions as long as they behave professionally and do their job well.

If this is a reference to discussions around IQ, I'd suggest that equating "person X scores lower on IQ tests than person Y" and "person X is subhuman compared to person Y" is a frankly horrifying position and if that isn't the equivalence you're trying to draw then you might do better being less combative and more descriptive around your actual objections.
