It's an accurate portrayal of the early Dutch settlers in The Cape. They endured unimaginable hardships, their fortitude and resilience was absolutely astonishing. The families that slowly pushed north were the toughest people on the planet. They didn't displace anybody either, there was a vast inhospitable emptiness, don't swallow the bullshit you've been told. The politicised version of what happened in the very early days is about as legit as Ann Frank's diary.

Granted that when their numbers increased and they got the hang of survival they started taking land and cattle from the local tribes, but prior to that what they did was bloody epic.
Everyone forgets that local tribes raided, butchered and enslaved each other quite regularly, but somehow it was more acceptable than when white folk joined the fray.
Spare a thought for the San, who got fucked over by everybody, but nobody likes to talk about that.
Don't be fooled, Africans and Moslems are not so slowly colonising Western Europe, its early days, but its happening. It will have to be called something else because colonisation just won't fit the narrative.
