My goodness! How can you honestly make such an assertion? I am American, I've visited every state and lived in a dozen of them. I am well-acquainted with many forms of racism and am fascinated that you could believe such a statement. All I can say is that you are unequivocally wrong.
> Don't wash the black community's suffering with white experiences.
This is absurd - finding common ground is the key to rooting out and overcoming things like racism. Always insisting that someone's experience is too different for others to understand only serves to perpetuate division.
I will never know what it's like to be a black person and all of the stupid things black people have to up with. But experiencing unkindness and bigotry helps me understand a little. And while having just a couple of experiences where someone judged me and was cruel to me simply for being white is nowhere near the same thing as dealing with it for years, it's something I can extrapolate from, and it taught me more about racism than any number of books or articles ever could.
