example one of racial discrimination is bullying for skin tone difference
example two is racial discrimination at work I.e. the boss gives out paychecks for the month the persons of lighter skin tone have pay checks that are bigger than the ones given to the people with darker skin
example two is school groups i.e. the teacher would split the class in four groups, and each group is defined by race and no one can change groups
example three is when two people of different race are arguing and person A says ''well I guess that's what someone *like you* would do/say''
