Necklacing: Placing a tire around someone's neck, filling it with gasoline and setting it ablaze.
Only a Stalinesque "useful idiot" would offer any amount of praise on that piece of satanic trash.
"THE ONLY GOOD COMMUNIST IS A DEAD COMMUNIST"
Let’s just say that I had PLENTY of reason for expecting him to be TERRIBLE. I’m not sure of the context of that image, but as a point of fact, Mandela was NOT part of the South African Communist Party. (And he doesn’t look thrilled with the banner behind him.) It was not until 2004 that the ANC identified as Social Democratic Party, and during the Mandela rule, the ANC was frequently called a neo-liberal (what Americans call conservative; free-market) party.
My best guess is that image is the product of some of the negotiations which led to the SACP agreeing not to split the black vote by running candidates against Mandela.
