I think positive privilege has to be considered, and seriously. It's not just about what is taken away from minority groups, there are, unquestionably, serious advantages given to people who are born into certain demographic groups. Sometimes, yes, privilege consists of merely not needing a handicap ramp that is inconsistently present and diificult to use when there. But here are other cases in which "special people" straight up have their own entrance to the building that no one else can use. And if you grow up as one of those people, then sure, you likely think of that as a normal state of affairs and may be offended and say "but what I want is for everyone to be able to use the special door not just me". But fundamentally, it may not be possible for everyone to use the special door at once. A deficit-only portrait of how privilege works fundamentally ignores the fact that the disproportionate amount of capital concentrated in the privileged classes may not actually be fairly redistributable without reduction. If that is the case, nominatively equal rights under the law are great, but cannot, on their own, actually create social equity where there is none.
I feel like you're arguing at me, as if you somehow think you and I are in disagreement? Am I inferring wrongly, or are you approaching me as an opponent in this discussion, Poli?
In regard to the rest... if you're talking about wealth, sure, maybe reduction is necessary if redistribution is your aim. But aside from an extremely few set of cases of "special doors", the vast majority of social privileges are NOT zero-sum. Most of the privileges are based on social biases and stereotypes, the expectation of behaviors and tendencies, lots of subconscious things. There's no reason that white people have to be treated worse by the cops in order for black people to be treated fairly. There's no reason that white people should face more suspicion while shopping in order for black people to face less. It's not like there's a fixed suspicion quota that has to be met

I genuinely don't know why you're lecturing at me.
