That a legal government of a modern democratic country cannot represent its people is a horrendous claim. As a strong believer of democracy, I'd rather assume that you were the minority in this case. The everyone claim may hold true for everyone you know (among the minority of your country of course).
As a strong believer of democracy are you naive enough to believe all the elections are perfectly fair, no party at power ever cheats to imitate democracy and that democracy is about everybody sacrificing themselves to obey "the majority"? Do you believe the Democratic Peoples Republic of Korea is actually democratic? Do you believe the Liberal Democratic Party of Russia is liberal?
As believer of HEALTHY democracy, I've never made any such implications. Guys from US/UK/EU claiming Taiwan is a country should go protesting right away, don't let democracy down!
As I already said, if democracy doesn't work in your country, don't waste your time caring about China/TW/HK unless you actually live there.
