Like this:
A government-sanctioned and enforced system of racial prejudice leads to a certain racial group lacking education, skills and a sense of self-worth, which in turn lowers their empathy towards others and their ability to realise the highly detrimental effects of physically abusing another person, which they will do in order to exert control over someone and thus feel more in control of themselves. (PLEASE NOTE this is a HIGHLY simplistic explanation of why some people rape.)
zulgin then goes: "Government-sanctioned and enforced system of racial prejudice? Sounds like affirmative action to me! Reverse racism FTW! People who suffered under Apartheid use it as an excuse to rape, therefore I can use AA as an excuse to rape! Yee-haw!"
(I'm assuming you think AA and Apartheid are just as bad as each other because they are both official forms of racial prejudice. In the same way that holding someone's hand is the same as having a week-long orgy because they both involve touching people...)
ek volg nogsteeds nie, am I suppose to start raping now?
