This is a new one. People are so used eto communism failing so bad that they can't recognize it when it actually happens. LMAO.
China is communist. They've found a way to make changes so it can "work" and their economy doesn't collapse, but it is communist. It's even more dangerous because they've managed to find a way to not bankrup the country this time. That's impressive and scary. Even awful ideologies escape.
Most people make the mistake of assuming that communism is an economical definition alone. It's not, that's Socialism. Communism is a combination of not only control of the economy but also the society. They are working to make it to its final state, which could or could not happen. But it's getting there: they already control the lives of every single citizen, dissidence isn't allowed. People who have tried to make business in China will tell you how hard it is to do so. Everything is strictly controlled by the government. Those who disagree, have to keep it silent otherwise, their lives will be ruined. The government tries to keep them "happy" so they won't stand against them, but that can't work for so long.
And of course, the main indication of a communist society is the elimination of any variation: the ongoing annihilation of Christians and Muslims is a way to get rid of different opinions that won't adjust to the established norm.
