You are asking to prove an unfalsifiable thing. The sources prove that the camps aren't camps, that Zenz is a liar, that Falun Gong are liarsz that Uyghurs aren't being forced to not speak their language, that Uyghurs are growing in populayion, that Uyghurs aren't kept out of political or cultural posts. Yet you still claim it might be going on.
There is no source that indicates a genocide is going on. The story of a genocide is going on has been proven to be propagated by liars. There is no rational reason to believe a genocide is going on, there is literally nothing indicating one is going on.
You continuing to want us to treat China as if it is committing one isn't based on one shred of fact, but instead because you feel like it might be possible. What you feel like isn't something that inherently deserves respect. It is honestly kind of racist how you keep insisting china is commioa genocide, despite all evidence to the contrary.

I have refused to engage with them? That's a ridiculous claim.

Instead of actually engaging with their content and acknowledging what they say, you move the discussion (as you are doing here) to one about what feel is happening.
