So here's the thing: Most "white" men distinguish in their thoughts between (a) Black people who are normal, innocent, law-abiding people who just happen to be "black," and (b) "n*ggers." They are not the same people.
When you see videos of individuals of black African ethnicity looting a Target, or destroying property as a mob, or committing crimes that harm people - usually Black people - those individuals are thought of in Category (b).
The police who are the subject of this action hold no hate in their hearts for Category (a) Black people. Indeed, they spend a large part of their professional lives actively protecting the safety and other interests of Category (a) Black people. Which is why they hate Category (b) Black people; those are the ones who are threatening and harming mainly Category (a) Black people.
So when a Cop or other "white" person says words to the effect that they would like to get rid of all the "n*ggers," they hold no animosity at all for Category (a) Black people and are talking about the criminals and trouble-makers within the Black community.
And if it were not for that odious word - N*ggers - one could say with some confidence that most Category (a) Black people feel pretty much the same way about those whom these Cops would refer to as, "n*ggers."
Would that we had a comparable slanderous word for worthless troublemakers who happen to be "white."
Are these cops "racist"? Not in my view.
