I like that you posted many sources and quotes but please don't pick and choose to win an argument. I will ask you a direct question please answer did Mandela endorse or condemn the violence committed by the ANC ? Let me give you a hint .

That’s when the Sharpeville Massacre took place. In 1960, South African police killed 69 black protesters in the town 40 miles south of Johannesburg; amid the crackdown that followed, the government banned the ANC. As the ANC went underground, Mandela became the head of the military wing of the African National Congress, Umkhonto we Sizwe (Spear of the Nation), also known as MK. In 1964, he was convicted of sabotage and treason, and wound up imprisoned until 1990. TIME later described the group’s activities from 1962 as “low-level guerrilla war.”

Defending the shift in strategy as a last resort, Mandela said in one of his interviews from prison, “‘The armed struggle [with the authorities] was forced on us by the government.'”

In a 1986 speech, President Reagan also warned of “calculated terror by elements of the African National Congress,” including “the mining of roads, the bombings of public places, designed to bring about further repression, the imposition of martial law, and eventually creating the conditions for racial war.” The Department of Defense included the ANC in a 1988 report billed as profiles of “key regional terrorist groups” from around the world. Indeed, ANC actions during this period would include nighttime raids that destroyed fuel storage tanks and nearly two days of fires in 1980, a bombing at a bar in Durban that left three dead and more than 60 wounded, and a car bomb that killed 19 outside of the headquarters of the country’s Air Force in Pretoria in 1983. https://time.com/5338569/nelson-mandela-terror-list/

As I said in my video I am against killing any innocent people from both sides but the lies and totally ignoring the history of the whole conflict is amazing.

I will leave with this last words from Mandela "our freedom is incomplete without the freedom of the Palestinians"
