Besides, do you really believe someone could talk with Pinochet for 45 minutes and thereby turn him into a monster? It's not credible. It's more likely Pinochet used Friedman for propaganda value, and stroked Friedman's ego. People who run governments tend to be users and tend to be masters at stroking ego.
I once had a conversation with a Senator whom I despised. He was incredibly charming in person. I can easily see falling under the spell of someone like that.
Frankly, you don't like libertarianism, which is your choice, but if this 45 minute conversation with Pinochet (for which no transcript exists) is all you have, it isn't much of anything.
I still think it's ironic that libertarianism's detractors claim it's both about no government at all and oppressive, authoritarian regimes. Clearly both positions can't be right, and likely neither.
Again, on the one hand you have someone who fled Chile and was murdered by the Pinochet regime and someone who flew into give speeches and pal around with the junta. I’m sorry if I weigh the account of the former more than that of the latter.
