Don't intentionally drive them out of their homes in an ethnic cleansing and steal their fucking land and kill them off every couple of years like 'mowing the grass'.

Maybe don't slaughter them when they try non violent protests.

Maybe don't have an apartheid state that south Africans that suffered under an apartheid state described as being worse than South Africa.

Oh, while we're on that topic, maybe don't give weapons to south Africa when the rest of the world is boycotting them for their evil, or test nuclear weapons with them?

Maybe don't try to ethnically cleanse your neighbors?

Sadly, I know all of those were apparently too much to ask.
