You do not fight racism with racism. You do not fight injustice with injustice.
I do not have a horse in this race but the history of Africa, particularly South Africa has always interested me. My conclusion is that Boers are really just another african tribe which just happened to migrate from a bit farther off. The "indigenous" people who now claim this status, on the other hand, are nothing else than more recent migrants. And they claim priority only on the basis of their race and the notion that your skin color determines whether you're "proper" african or not. I find this idea obnoxious and hateful in the extreme.
The lakmus test for racism is very simple: if the races involved in this situation were reversed, would you consider this racist?
