None of this passes the so-what test.
Okay, so Pinochet was pro-capitalist.
So what?
When agoraphobic people bring up Pinochet, they are using guilt-by-association to condemn capitalism. But why? Hasn’t every nation, every religion, every ideology had its fair share of villains? If anything, capitalism has had far fewer fascists than other causes.
It would be one thing if Stalin, Hitler, Mussolini, Castro, and Saddam Hussein had all come to power through free-market policies and rhetoric. But they didn’t.
All they have is one horrible dictator to shove in our faces. Just one, which they use over and over and over again, as if that somehow proves that fascism and capitalism are joined at the hip.
Wikipedia has an article on what is called “reducio ad Hitlerem”. It is classified as a logical fallacy, for good reason. I see no reason why reductio ad Pinochet should be given a free pass.
