It's not a secret that China is run as an authoritarian dictatorship. Xi Jinping cannot be ousted in an election. He appointed himself for life, and regularly purges anyone who might usurp his power. They don't have a functioning democracy. Are you seriously disputing any of this?
None of this excuses issues with American democracy.
America is not technically a democracy. It’s a Republic
Why are you responding to a comment about how bad the USA is by talking about how bad China is? Do two wrongs make a right?
