I think I read a comment from someone here a few months ago telling of a conversation with a Vietnamese or Chinese comrade on a similar subject. They were asked how they felt about the free speech people enjoyed in the US and they said that the way Americans that were so proud of their free speech and treated it like a gift from God used it was just to call the president the n word and to be horrible to others without consequences. Meanwhile the people of the US didn't have the liberties to live in their own house, to have healthcare, an education, or all the other things their government guaranteed them in their country. So while it would be great to have the right to freely criticize their government, it's definitely nowhere near as important as having the freedom to live a decent life regardless of what family you were born to. Another good point people are bringing up here is that civil liberties in America are fictional anyway, and vanish away the second you pose a threat to capital. And yes, above all, show him the clip of Parenti's yellow lecture where he talks about liberals crying out for the civil liberties of the fascists in Cuba after the revolution.
