When I lived in China in the early 1990s, there were things that you could not discuss. One was Tibet. Another was Taiwan, “referred to in my daughter’s public elementary school in Shanghai as “China’s largest island.” Another was the 1989 massacre of students and workers in Beijing. I used to be grateful at the time that I was an American and that back home, we could talk about anything.
Except that in a way we can’t. Not in public discourse, anyhow.
