If one was argumentative, and one is... because it comes with the name. You could say that this isan abuse of power.... you're asking your staff to consider your world view to be both correct and enforceable - and you're doing so from a position of power. You're the boss. You can end their employment or make their lives very difficult. So are they really examining their whiteness and privileges - or are you using your economic privilege to create a situation which suits you?
Could it be that when you get into your next community forum and staff meeting you're going to mis-interpret and paraphrase everything white people say because you're applying confirmation bias to the situation? Is this really true? Or do other people from all races do this - but you don't see it because your brain is wired to only see what you want to see What you've done in this article is berated white people for behaviours you've exhibited, you've paraphrased and explained what 'white people' think and how white people are educated and how 'white people' have superiority complexes. If I had a boss who exhibited this sort of thinking about any one racial group they had power over, I would consider a letting to HR.
Here's the challenge to you (without taking offence). Go back to your office and do a scientific test. Don't base your assumptions on 'upholding justice' - because your feelings are skewing the information you collect and the information you're interpreting. Go back and set someone in your team to do an actual scientific test.... controlling all the variabilities for inherent bias. This is what humility and a commitment to equality and fairness looks like. You want to fight for justice and equality, you need to be sure you aren't making things worse. For your white employees who have to deal with a powerful Xicana boss who writes in such disparaging terms about them... like they're insufficient little children who must be guided towards an enlightened world view... I suspect you're making race relations worse rather than better.
