Which is exactly what Trump is ending with DEI ban.
Trump is actually the president that is making institutional racism illegal.
As for racial rules, what you are talking about is really affirmative action, which was ruled unconstitutional in 2023. Through the legal process, most importantly. There are arguments that you can make on both sides, but just so you understand the idea for affirmative action isn't to punish whites, its basically to inject diversity into campuses so people become more homogenius (which is a good thing) and you have things like kids from racially poor communities getting a chance of getting a degree getting a start at building generational wealth. Its been proven many times over that if you prop up the lower class of the population, everyone benefits. While affirmative action isn't the best way of doing this, its far from bad - plenty of studies done on this.
However, Trump is not ending institutional racism, he is basically axing funding for programs in schools that align more politically left with a shotgun approach, not giving a fuck about cutting actual programs that may be of value to society. This is vindictive punishment of a man child that lost in 2020, probably coupled with some racism (because Trump has a record of being racist against black people)
Whether the goal of those rules is to "inject diversity" or not does not change the racial hierarchy.
