Yes, I'm lucky. I was born a white man in an occidental country, which is admittedly a privileged position.

Also, I'm living in a country which still pretends to be a democratic republic, so blatant oppression of free speech is politically more complexe.

If capitalism plays a role in all that, it is more often to threat these liberties than anything else. Plutocrates are on the rise, and they want trade secret to protect their businesses from republican values and dream of always more defenseless labor forces that are not granted all that cumbersome rights that democratic freedoms grants.

Is capitalism a solid ground to critic CCP? Not necessarily, trade with China to access its cheap oppressed working force seems to be a good deal from some capitalist point of view.
