I think other people have given good answers, but something I didn’t see anyone touch on is the cultural erasure aspect of chattel slavery. A concerted effort was made by slave owners and others to erase the culture and history of the people they kidnapped and sold. Families were split, languages were suppressed and a lot of that history and cultural identity was intentionally d destroyed. That is part of why American racists hate “black people” instead of Kenyans or Ghanaians. It is both a failing of their worldview and a generations long strategy.
I think American stalls are designed that way specifically to make them less private in the hopes it will keep people from boning or doing drugs in them. Just another facet of American life made worse with puritanical/punitive culture.
