That's not what free speech is. It is a concept that lives far beyond what's written in a document.
You can violate free speech all day every day in full view of the world and them having taken very articulate notes on your violations and not see a single day in court or jail.
But then, my criticism of the people's criticism of Tan's free speech is also criticized. And then we only get criticism of criticism and no actual productive dialogue. Or so it seems. Looks complicated. Where does it end?
