Calm down dear, your brain will overheat.
I know people like you think history is something some sociology professor made up five minutes ago, but here's a historic fact for you. The first slaves taken by Europeans to work in the new American and Caribbean colonies back in the 16th century were white. They were European convicts and prisoners of war. So where does that leave your sentimental wittering about slavery based on skin colour.
When the tropics climate proved hostile for those people and they began to die, the pantation owners looked elsewhere for, to put it bluntly, a product better suited to the needs of their business. I chose my words there to illustrate how the planters regarded slave labour - as a commodity. It didn't matter to them what colour the slaves were. The forced labour that was part of the penal system of British, French and other European prisons was equally dehumanising yet the vast majority of prisoners (if not all of them) were fair skinned.
Did you know that in Britain bat the end of the 18th century a child of six years or over could be hanged for stealing a loaf of bread. Or that chilren convicted of trivial offences were forced to workl on treadmills for fourteen hours a day. Did you know that women convicted of prostitution or theft in that era were made to uppick the tarred rope reclaimed from the rigging of sailing ships for fourteen hours a day, and had to do that work day after day, even though the wounds on their fingers became septic and eventually gangrinous. Nobody care when they died, they were only poor people.
220 years ago the world was a horrible, brital place and it wasn't just slaves and convicts who suffered dehumanizing treatment. What about the pretty daughters of wealthy merchants or aristocrats peddled by their fathers for monery, influence or business advantage, into marriage to old, fat, ugly and often diseased men. Were their lives not dehumanising? Or did they, like the convicts and prostitutes not matter to someone like you because they were fair skinned and thus had "white privilege."
Slavery was based on economics and practicalities. Criminal justice was based on the fear of the rich and powerful that if the poor were not kept in a state of subjugation they would rise up and overthrow their superiors. As I said the world was a horrible, brutal place. You make the typical liberal error of viewing the past through the lens of the present.
As for America's race problem, don't you understand people like you, diven by emotion rather than logic, are the root of the problem. Your self righteous outrage sows division and resentment.
Your self loathing is regretable, but that's your problem to fix. I suggest you start by reading a lot of history, none of which should be written by American liberals who simply do not grasp the concepts of historical accuracy and objectivity.
