The reality is, some Black Africans coming to Western(ized) areas have trouble with punctuality. In their inferior cultures, to say "8am meeting" means that 8am is when one is to start getting around to go to the meeting. That might mean they are 10 minutes late or two hours late. It simply depends on their situation at 8am and their own personal style. So obviously, "urgency" is something they have trouble with, and thus is a "racist" White value.
Now you know why Black African societies could never succeed before White colonization.
The people in the video completely fail to understand this.
