White Fragility question

How did racism change and adapt after the civil rights era? Consider attitudes as well as behaviors.
Why does the author say that white progressives cause the most daily harm to people of color?
Why does the author consider young white people today to be no less racist than white people in the past?

"One line of King’s speech in particular—that one day he might be judged by the content of his character and not the color of his skin—was seized upon by the white public because the words were seen to provide a simple and immediate solution to racial tensions: pretend that we don’t see race, and racism will end. Color blindness was now promoted as the remedy for racism, with white people insisting that they didn’t see race or, if they did, that it had no meaning to them. Clearly, the civil rights movement didn’t end racism; nor have claims of color blindness. But reducing King’s work to this simplistic idea illustrates how movements for social change are co-opted, stripped of their initial challenge, and used against the very cause from which they originated."

I think this idea of not seeing color is something that I grew up with. I don't remember my parents ever saying this phrase specifically, but it seemed to be a prevalent thought. Perhaps I was in my late teens or even in college before that idea shifted for me...that to see color is important because it shapes the individual, it is part of identity--not the absence of it. So this quote from Dr. King that we've seen and heard so often--to consider it as having been hijacked to perpetuate our own whiteness and power is troubling.

Young white people today can be no less racist than their ancestors because it is so deeply embedded in our society. If the people of my parent's generation didn't recognize implicit bias--how could they have taught us?

Here's an example from my own thought process. If I see a white man, well dressed, driving a BMW I think "Oh he's a banker or lawyer." If I see a black man in the same car, I think "Oh, he must be a drug dealer." These are thoughts that flit through one's mind without a second glance...unless we practice a deep attention and mindfulness to exploring our biases and UNLEARNING them.

When we moved to Roanoke our realtor said, "oh you'll definitely want to live in the county, they have the best schools." I.e.--the city schools are not as good. Why? The city has rundown neighborhoods, many black people live in the city. The perception is that drugs are more prevalent in city schools and they have less resources available to those schools. Grandin and Raleigh Court are great neighborhoods for white people--especially if you don't have children who will go to the city schools.
So here we are, living in the county. Our elementary school is ranked one of the best in the area. We have a few black families on our street. The ones closest to us are of mixed race I think.
