Where does it say that black men are more aggressive, and further, that it&#x27;s a strong enough association to be useful?<p>It does say that “A deficiency in monoamine oxidase A (MAO-A) has been shown to be associated with aggressive behaviour in men of a Dutch family”, so it sounds like there are some Dutch people you wish to discriminate against.<p>And &#x27;59% of Black men, 54% of Chinese men, 56% of Maori men, and 34% of Caucasian men carry the 3R allele&#x27;. Which form of discrimination do you want to apply to the men in the US with Chinese and Caucasian history which also have this allele?<p>The category of &quot;Black&quot; is very diverse, because &quot;Black&quot; does not have a basis in biological diversity. If people of a Bantu heritage have very different allele distribution than those of Igbo heritage, then won&#x27;t you be needlessly discriminating on the secondary aspect - black skin - rather than the primary one?
