I know for some courses and tickets they need a lower % to pass the final test/course. Personally I would say that is racist and insulting suggesting FN do not have the same mental capability of other races so they are held to a lower standard
Then take in some cases when a FN is charged with a crime they receive a lesser sentence because they are FN. This again is racist suggesting FN are not capable of knowing the difference between right and wrong
This is just two examples but this racism is ok lol
