Yeah, I thought the rubber might hit the road and expose our disagreement on this.

Iran under the Shah was a strongly US supported capitalist dictatorship, as was Marcos' Indonesia; in Latin American, many democratically elected socialists were systematically undermined by US policy and arms. For all of his instability, Trump's campaign support for Putin, dictator of a crony capitalistic state; and for Al-Sisi in Egypt and Erdogan in Turkey is US foreign policy as usual. No other western US ally has congratulated Erdogan descent into a capitalistic dictatorship, via a referendum condemned by neutral international observers as fundamentally non-democratic. 

And yet the delusion persists among the public, that US foreign policy is driven by a desire to spread democracy.
