I have been there. I went on a business trip to visit our offshore development office in Beijing. A few of the devs went sightseeing with me one weekend and we ended up going to see the forbidden city. The cab dropped us off at Tienamen Square and I asked if we could spend some time there before going across the street. There was general consternation as to why I was interested in such a boring place. I said I wanted to see where the iconic photo of the man standing in front of the tank was taken, just to pay my respects to such an act of bravery. Not one of the six Chinese devs had ever seen that photo or had any knowledge of what happened there. That history has been censored so completely that very few Chinese are aware of it.
You can't be democratic with that level of censorship. A functioning democracy requires and informed electorate. For proof of this, look no further than the recent US presidential election.
