Save me the pearl clutching. The song was penned by people living directly under the thumb of those poor innocent descendants and waging an active battle for their freedom. You'd even deny them their rage against those directly culpable for their oppression.
Poor innocent descendants -> I did not call them poor, or innocent.
Deny rage -> of course not. I'd be furious too.
But singing songs like "bring my machine gun" and "shoot people from that ethnic group" just aren't justified, especially since South Africa has been a democracy for decades now.
Moral relativism at its finest. Turn away now, because this is a dead end my friend. "ethnic cleansing is justified if the violence goes the way I prefer" is the red flag of all red flags.
I guess, except that ethnic cleansing bit is something you just made up. What is actually happening is that you've been memed into caring about the winners of a justified war singing their old war songs.
