I like the tone of your reply (huge improvement 😉), which makes me willing to engage you. I think however,  that you miss the point that the violence pre 1994 elections were state sponsored with FW at the helm! Therefore there was no need to prevent what he was the mastermind of. 
So far as your comment regarding Madiba is concerned,  allow me to throw an old 'faithful' at you: "One man's freedom fighter is another man's terrorist". If we are to minutely measure the deaths and destruction caused by the hands on both sides - 3 guesses who would win! Madiba and many, many others would not have walked the paths they walked had it not been for the forced oppression of one over another.
And I will watch The Tainted Hero's  movie - and struggle through it, if it is one-sided, in the hope of understanding people who hold similar views to yours.
