Yeah, that's odd. I would think protection of the sort would apply to all.
I think this is the core question about attempts to formalize and codify protection for segments of the population that are experiencing discrimination.
It's something I changed my mind about on a per-topic basis when I was in my 20s. For example, I had disagreed with a philosophy prof about the importance of the US proposal for an ERA (Equal Rights Amendment). It was an attempt to spell out in plainer words that 'equal rights for everybody' included women. I couldn't understand why additional legislation was necessary, 'everybody means everybody, it's already the law'.
But I observed that when my rival pays a black engineer 25% less than her equally qualified male counterparts, when I hire a black engineer at 100% in my firm, I'm not fixing the problem. Black engineers are still getting paid less. Multiply that by millions of transactions, and it's a demographic income suppression even if 90% of the hiring managers are like me and wouldn't even consider it.
The problem is: the number of active racists is above the critical mass or threshold required to accelerate racial differences in opportunities; there's too much inertia for there to be a satisfactory resolution in human lifetimes (an example being my dad's golf course above, but substitute with the 1500% gap in white vs black [
family estates] and their connection to tuition affordability), and my modelling that shows that small differences will probably grow over time in an unregulated environment, despite a majority of fair citizens.
The critical mass thing is basic modelling. Sort of like how we don't need to worry about a few vaccination avoiders... but when it reaches a threshold, it becomes a public health hazard. Same with bigots. A few are a joke. Above a certain percentage, there's an inevitability that target demographics will have no equity, no standard of living in 10, 20 generations. That's because when you and I treat people fairly, they don't gain over the average; but when somebody treats them unfairly, they lose versus average. Over time, this accumulates, and it seems to be exponential (as they lose assets, they lose the capacity to preserve the remaining assets faster). Just being fair doesn't compensate.
It's one of those "this is why we can't have nice things" things. Protection applies to all. But there's people who disagree with that, we have to push back in order to achieve the fairness that is offered in the nation's vision.
