I think that's the internet in general that turns things to the extreme. I browse /pol/ and never does anyone say it's a wasteland or a war, infact most saffers on /pol/ deny the white genocide America tries to use, but admit that white farmers are targeted at high rates.
But the difference is that /pol/tard saffers aren't blinded by what could happen. Neighboring countries are a clear example of how fast things can deteriorate and the mob mentality that arises when a group is blamed for the problems (white people in SA case, the gukurahundi in Zimbabwe's case)
And with the same threats of taking land and the fast rise of a communist party with a dictator such as Zimbabwe, it's pretty foolish to say everything is perfect here.
As i said before, everyone still tries and maintain a normal life. And when you're living in Cape Town which is one of the highest tourist destinations in the world, it's pretty easy. But south africa isn't just one city, it's pretty big, and the demographic and history differs throughout the country. You can't compare the life of someone in KwaZulu-Natal to that of a rich Capetonian who's rich enough to travel regularly even with our dwindling currency.
