It's exactly the same conclusion I came to after years of dealing with the weird psychology some people illustrate about South Africa, and elaborated by a clearly intelligent individual. I posted it before but it deserves a re-post. For context this was after me bitching about being banned from a site for spreading the message of tolerance.
You mustn't let it get to you. Sod mybroadband and other bs blogs with an axe to grind. There's no way you can get a bigot to change their mind, you're wasting your time and energies there. They're losers trying to control other people's minds because their own lives are out of control. I Luv SA are now just as bad as SA Sucks because they also harp on and on about everything being negative; it's called confirmation bias whereby any information is qualitatively slanted according to that person's perception. Most of them don't even live in South Africa anymore, they just want South Africa to fail to justify their own decision to emigrate. The UK isn't such a great place. The Ozzies aren't all that friendly. Canada is freezing cold. The reason they bitch on about South Africa is to make themselves feel comparatively better off. And that, I'm afraid, is what makes a lot of people tick: if they think they're slightly better off than someone else it makes them "happy".
