"Racism" as a tool for social change has outlived its usefulness, IMO. Back in the day, branding people as Evil for supporting racist policies was worth the side effects. Jim Crowe laws, "separate but equal", and the other issues rampant in 1950s America were terrible. If we didn't hand out anti-racist good guy points and pro-racist bad guy points, we'd never have cared about expending effort on fighting the terrible injustices of the time.

The problem is that the anti-racist strategy has slowly morphed over time to fight things that are less and less terrible. Theres a ton of pointless Culture War bullshit that really isn't important enough to have super high stakes in terms of being a Good Person. Whether or not you participate in a campus Day of Absence. Whether or not you like Marvel making a black Captain America. Whether or not a video game has enough racial diversity. The concerns are often just so completely petty that I just want to opt out of the whole system, commit myself to simply treating people fairly and being a good person, and get on with my life.
