The CCP is basically China and at least most Chinese people, because it draws its authority and power from the complacency of its constituents. Trying to differentiate the CCP from its subjects will leave you labeling all counter-parties as communist agents until you’ve realized you’ve labeled the majority of Chinese citizens!
Of course no country’s government has the full support of its citizens, but to say Chinese people are wholly distinct from the CCP is disingenuous.
There is no ruling ethnicity, just a more unified single party system. People can choose to participate in politics, they just have to do it within the party.
