WTF is that supposed to mean.
Every 40 years or so, Americans have to go through some form of racial reckoning, because they refuse to acknowledge or deal with systemic racism. Things get better for a while and then there's a white backlash which, having never learned about the past, they try to "their place".
You had the Jim Crow Laws 40 years after the Civil War, then in the 1920's, you had the race riots and massacres in Oklahoma City and elsewhere, which I hadn't even heard about until the last couple of years. Good job at burying that stuff. In the 1960's you had the race riots which lead to the Civil Rights Act. In the 1980's you had Reagan cancelling the War on Poverty, Zero Tolerance on drugs - but only for blacks and Hispanics, and a complete backlash against black rights.
Now, another 40 years on you have the George Floyd riots, and you're trying to stop white children from learning about racism. You don't want white children feeling bad about themselves on account of being white, but you don't have any problem at all calling black people stupid, lazy or criminal, and zero tolerance is still in vogue, but only for black kids.
Think about it like this. You buy a hotel with no disabled ramps, and no facilities for disabled people in the washrooms, or the guest suites. The law requires public spaces to have access for the disabled. You claim it's not your fault the hotel doesn't have access for disabled people. You didn't build the hotel and it was like this when you bought it. But it is your fault because you're now the owner, and you've done nothing about the situation since you bought it. You could have installed a ramp for access, and set aside some rooms with wider bathroom doors, and handicapped railings, but you didn't.
When you're aware of a problem and you do nothing to change it, YOU are responsible for the problem.
