The ANC repeated its position that the armed struggle against the country's white-ruled government, which began in 1960, was a just war and that civilians had not been deliberately targeted.
But the ANC statement said some of its guerrillas weren't sufficiently trained and "were never thoroughly under the discipline of the ANC."
Avoiding harming civilians was a deliberate modus operandi of the ANC, the same way that Hamas deliberately kidnapped civilians. They cannot be blamed for attacking military bases - they should be blamed for attacking that which was neither military bases nor infrastructure.
That also serves as a response to his blabbering.
"Aren't you ashamed that you should have worse intentions for yourself than nature had?"
"My dude, you literally live in a barrel. And cover yourself already."
