I'd argue it's ultimately a much more effective way to combat racism/bigotry/whatever, unless you accept the Critical Race Theory definition of racism, which I do not.
The military is probably the best evidence that this works. They take black, white, hispanic, and Asian Americans and put them through rigorous training together. In the end, nobody gives a crap what the other people look like or where they came from - they're your brothers and sisters and you trust them with your life.
Dehumanizing people, calling them out, invoking the mob, getting people fired... these are all tactics that are doomed to stoke animosity, not reduce it.
