&gt; That&#x27;s like saying that aliens exist as a cultural construct.<p>No, its not. Its more like saying color exists as a product of perception. Races are a categorization, categorizations do not inherently exist at all, they exist as products of mind only.<p>&gt; How would you call the unscientific belief that races exist in the human species, if not &quot;racism&quot;?<p>If by that you mean the unscientific belief that the cultural perception of race has a direct correspondence to inherent biological feature of humans, I&#x27;d call it something like &quot;the erroneous belief in biological race&quot;.<p>Its pretty much logically orthogonal to racism; racists are probably more likely to believe that biological race is a thing than non-racists, but its quite possible to be a racist without believing in biological race (if it weren&#x27;t, bigotry against, e.g., nationality -- which doesn&#x27;t have the problem of people mistaking for an inherent biological trait -- wouldn&#x27;t be a thing. Heck, bigotry based on sexual orientation seems to be <i>inversely</i> correlated with the belief that it is an inherent biological feature.)<p>&gt; Errors need to be pointed out, not accepted in silence, even if the hoi polloi will make you pay for it.<p>Well, yes, that&#x27;s why I am pointing out the error of your mistaken confusion of the erroneous perception that race is an inherent biological feature with &quot;racism&quot;, a term which has always referred to belief in the <i>superiority</i> or <i>inferiority</i> of particular races, not belief in the biological inherency of race.
