If what you're saying was really universally true ("no one cares") then mankind would have gone one step back.
To be clear, just about everyone in the world, with the exception of your true KKK types (0.0000001% of the population), cares about being non-racist. And all of those people are, in fact, not racist at all. That only applies to the real definition of racism.
On the other hand, the left has defined “racism” as “someone that I don’t agree with”. Economic policy, political policy, foreign policy, if you don’t agree, somehow, with some twisted form of logic, you are a rrrrrraaaaacccist! That’s the bullshirt nobody cares about any longer.
In this case - any other conclusion that Chauvin was a racist cop, out hunting blacks, and - to the left - you are a big fat racity racist.
