I’m sorry you see this as an issue of personal credibility. It was certainly not my intent to convey that.
Everyone knows the cultural and political cesspit that is China.
It was the assertion that there are multiple biowar labs in China outside the control of the central government. And their plans to use it against their fellows. And the assertion this virus originated in one of them.
Those are the points I was diving in to.
As for their creators' plans to use the stuff on each other in civil wars after the CCP collapses, that is quite normal given Chinese history. Such local potentates have been looking over their shoulders like that for several thousand years. It's even a standard meme in Chinese fiction.
