And I can't do anything about it much more than walk around with a Keffiyeh or "flip the bird" at :estonia-burning: displays of Pissreali flags. 
At least in Johannesburg, I had the option of violence. I know I constantly say "pelt Zionists from my high-rise balcony with a cinderblock" as a meme, but when I inevitably move back, I'm going to confront any genocidal Apartheid supporter who I cross paths. Maybe not actually with a cinderblock though. I'll start carrying around my Big Black Book on why Israel is peepeepoopoo according to South Africa.
