And the Zulus have been the political allies of the Afrikaners for a long time...yet another fact you are blithely unaware of.
If you can't afford to buy books...most places still have free libraries. I suggest that you avail yourself of the use of same.
I am perfectly aware of what the word "kaffir" means. It is Afrikaner for "nigger". And an attitude that makes "alliance" impossible. Alliance against what ? What possible common interest could Zulus share with white supremacism ? Gee, that's funny. I know South African police created puppet Zulu "vigilantes" during the township uprisings because in classic white supremacist thinking they genuinely believed that they were "good masters" and the Zulus were their "loyal blacks". In classic white supremacist thinking, convinced of their own goodness, they thought their "loyal blacks" would turn against the "outside agitators". It was as delusional in South Africa in 1989 as it was in Mississippi in 1960.
Perhaps you should try to read some books and free yourself from self-flattering delusions.
