I completely agree with you. The problem is with that intent to cast guilt on descendants solely because of their color; not to actually assign rightful blame. It is racism of the worst kind.
It is the primary reason why ‘diversity training’ is complete bullshit.
The underlying reason falls into the line about “the slave dreams not of being free, but of being master.”
And what would be an example of "rightful blame" based on whiteness alone?
