And I would state for a fact that you're being an ableist (not only in your insistence of intelligence being related to racism, or the ridiculous idea that education levels have anything to do with so called intelligence, but also in your framing of disability as a negative thing which I should not be calling people. As a disabled person - fuck you), and also harming the fight against racism, a system which is not only perpetuated by people throughout society, but was created by those in power, who are almost never what you would call "stupid".

You can continue to double down in defence of your own ego, or you could challenge your bias, admit that you don't know everything about everything, and actually listen to people who know what they're talking about:
