> we have defined treating an individual differently based on their race as a moral wrong. The act is wrong, regardless of your motivations

No, I don’t think so, You’re conflating racism with discrimination. We humans discriminate positively and negatively all the time. People discriminate based on race and gender and age for the purposes of picking a life mate or sexual partner, and society has exactly zero problem with that. Discriminating based on race is absolutely not a morally wrong act regardless of motivations. Intent matters, and the situation matters.

This talking point about all discrimination being wrong is fairly popular, and there are a lot of people who can’t see the difference between positive discrimination and negative discrimination. This is one reason I think affirmative action should end; it’s too subtle of a distinction and we were too successful at planting the idea that discrimination is bad.

You’re also conflating law with mores in your example. There are cases where stealing something is moral, regardless of whether it’s legal. There are also cases where stealing something is legal too, for example you can legally take back something stolen from you if you do it non-violently.

I was referring to humanity, to all of us.
