the resolution of people fighting for their rights is that they want to be treated equally.
That is not entirely true...people may want to be treated fairly, even if it is not exactly equal. For example I am 6 feet tall so I have no problem reaching the top shelf in a grocery store. My wife is only 5'2" and constantly has to ask someone to reach it for her. If the cheapest items are on the top shelf, that treats us equally but it is not fair. Having stepstools available for shorter people is one way to make it fair, but you would argue that offering stepstools discriminates against tall people.
Quotas were mostly an instrument of discrimination and that has not changed. You don't treat people fairly by making skin color a relevant attribute to determine fairness, that is true for any intrinsic characteristic.
And there are "injustices" you cannot equalize without significant oppression of others. Tallness, beauty, charisma... how would you ensure fairness here?
Colorblindness works in most parts of the world. The recent pop-"enlightenment" leads to much strive. Justifiably so. Reason for that is that it is wrong in my opinion because it is racist. The tendency for self-victimization is a path to even more racism, but that is another perspective.
Accessibility touches the subject of justice too but doesn't fit here as an argument, because ensuring equal access doesn't require discrimination, has a defined goal and is ensured and completed at some point.
Citation please? I bet it only works where everyone is the same color (Norway?) or where there is a mix but no history of one class oppressing another (Singapore?). In most places that come to mind, color/class is still an issue where oppression has been the legacy (South Africa, Australia, US, India, China). The hard part for the formerly oppressed is when the former oppressors say "let's all be equal now" after centuries of having an advantage
