On the subject of race. Why is there a tacit assumption that all persons are
I agree with Richard. But there is also another sense in which racism leads people to underestimate the number of 'whites'. I am thinking here of the practice of counting somebody as unequivocally 'black' if their ancestry is half European and half African, or even 80% European and 20% African. If skin colour were not considered to be socially and politically significant, this would make no sense at all.
