I think that one thing that some people are failing to look critically at when they compare the Apartheid conditions of South Africa with the post-Apartheid conditions, and indeed anytime any permutation of the words "Africa was better off under colonial rule" are written, spoken, or thought, is that we know from history that colonial rule creates this kind of violent, conflicted reality, and that it is almost an inevitable aftermath of colonialism. Much like beating and abusing a child may create a sociopath, disrupting and oppressing a culture creates a fragmented, damaged culture with sociopathic elements.
We KNOW the damage that colonialism and occupation wreak. They create profoundly complicated situations that will take centuries to correct, if they are correctable. There is no simple answer.
Totally not true. Look at scotland. We were colonised and we're a model of peaceful happy rainbow joy
