No, that's just how they are different from us. America is not the Republicans or Democrats. The Republicans or Democrats are no more or less legitimate in power than out.
That is not true in China. China is the Communists, the Nationalist, the Qing, the Ming, the Manchu, the Han, whoever is running the country is the country. You can't oppose the government and not oppose the country.
I realize that sounds odd, but that's how its been for millenia.
