Plus it seems odd to me that anyone on the left would prioritise injustices from centuries ago when there are many racial injustices in the present that need fixing first.
Such as the preponderance of black people in prisons being compelled to perform free labour for commercial companies. Is it the case that, while white people are more likely to use drugs, back people are far more likely to be convicted of using drugs?
We have a similar situation in the UK where poorer black people in London who use cocaine can spend many years in jail, whereas wealthy while people who use cocaine are considered good candidates for prime minister.
