Lets look at a few facts:

Mandela was imprisoned for conspiring and supporting acts of terrorism, mainly the blowing up of infrastructure (power lines) plotting to place bombs in public places (railway stations etc.) and stockpiling explosives and weapons to carry out terrorist attacks.

He was not imprisoned for opposing the South African Government.

Had he been convicted of the same crimes in the USA, he would almost certainly have received the death sentence, in Canada or Europe, a life sentence in prison where he would probably have died years ago.

Approximately double the number of violent deaths have occurred in the 13 years since 1994 when Mandela was released from prison as occurred in the 46 years under White rule from 1948.

As many as an estimated 5000 of those deaths were murders committed by Mandela’s ANC on Black South Africans of the Zulu people by the “necklace” method. A gasoline soaked tyre set on fire around a victim’s neck while he or she was alive.

Mandela’s wife at the time, the murderous Winnie, proudly shook her box of matches on national TV proclaiming “If we cannot win with the ballot box, we will win with the matchbox”

Add to those around 1000 White farmers murdered each year, many politically motivated in a strategy to drive farmers off their lands, impoverish farm workers and intimidate rural voters.
