I’ve not heard the term “racialism”. But institutions are built and operated but governments, and in America, if you look up those who made the laws that structured the institutions, it was all white men from 1600 to 1965 (99.9 percent of governors in British colonial times and elected white men in American times). It’s not delusional to say law structure society. Unless you like driving 65 in 35 or 95 in 65. But then again, those laws that structured the rules of driving and passed by government might be a fabrication like the negro act of 1740 in South Carolina.

That Negro Act law stated it was: a “Bill for the better ordering and governing of Negroes and other slaves in this province.” The law prohibited enslaved African people from growing their own food, learning to read, moving freely, assembling in groups, or earning money. It also authorized white enslavers to whip and kill enslaved Africans for being "rebellious." That doesn’t sound a bit institutional white racism in singling out “negroes”?

Think about it this way: that white male made law gave the allowance for whites to beat of kill blacks, and structured society as such. The Negro Act in South Carolina in 1740 amplified structural racism until 1865 in that state by allowing white men to beat and kill negroes for appearing "rebellious". Now imagine if you had to live under that law as a black man. Each beating you got would not be a false view but a deep cut. The murdering went on after that of course, illegal, though very whites were arrested and those that were acquitted.
