You have to realize that for young people from comfortable circumstances who have never themselves suffered much from political oppression, the U.S. these days is not a very alluring representative of “censorship-free liberal democracy.” They sometimes point to Trump and his followers as an example of where all that leads.

They have more admiration for the California climate and air quality.
But things do indeed get interesting when there are also Tibetans in the class.
