Most of the claims have nothing to do with Adrian Zenz, and I’d love to know what you have against him since his reporting seem to be factually accurate.
This person is making the extraordinary claim that all the provided evidence is bullshit, but ironically delivers no substantial evidence themselves, besides asserting "extraordinary claims require extraordinary evidence".
In this context you cannot find any sources that cannot be construed as shady in some way since none of them are official. You of course know this, and you will just question any source thrown at you, as you did previously. So why are you even asking? What's your point? That we don't know for sure whether the CCP is bad? Constant lies and not letting people leave the country aside, how many more screaming indicators of abuse do you need?
This is what cognitive dissonance looks like.
