So, we all hate racism. At some point, the efforts to quash racism became racist. I mean this in the sense that they force you to focus on belonging to a race, confronting the fact that you are a member of that race, and then accounting for whatever privileges or violations attach to you because of your membership in that race. This is at best counterproductive because it preserves the idea that "race" is something important. In fact "race" is a fiction dreamed up in the early Renaissance to justify the re-introduction of slavery to Europe. We should be striving to eliminate the concept, not further ingraining it into students.
Here's a piece by David Marcus that takes on the idea that everyone should be made to accept their race and confess their privileges. It's a very solid article on why this approach is backwards, and is actually making racism worse.
It's similar to the way in which the Democratic Party's electoral strategy of focusing on advancing the interests of minorities paved the way for Trump's electoral strategy of consolidating the white vote as a bloc. Indeed, many of the things Marcus warns against are much further along than he himself seems to believe.
