And yet another day that I am very convinced that while the USA accuses China of human rights abuses, the USA is busy doing the same but worse and even more crazy
You're conflating two different things - random crimes and government-led policy.
I'm happy to be corrected, but I can't remember when a government criticised China for its domestic crime situation, except maybe when its citizens were victims of a serious crime. Which is often a standard response. NGOs may criticise the CCP for something like the lack of rape convictions/lack of seriousness given to rape, but they do that for lots of countries including first world states too.
In contrast the vast majority of criticisms of the CCP is of the policies it brings in. So unless you're going to tell me that the Biden administration paid or ordered this homeless man to attack the woman, I have no idea why you've made the comparison.
while they can never provide any real evidence that China has done such things
Most of the things the CCP does is fairly open or it admits later and blames on "rogue officials". E.g. organ harvesting of prisoners. For years the CCP denied it happened at all. Same with the Zhengzhou tunnel flooding, the CCP refused to allow discussion of how many people died, and it was fairly obvious the death toll was being covered up. National media reporting quickly shifted from the dead/victims to rescue and clean up efforts. Now the attention has moved on, the CCP has punished "local officials" for hiding the death count, when in reality central Party members had to be complicit in ensuring traditional and social media did not focus on the issue, deletion of comments on dodgy stuff like the blacked out buses that were obviously being used to hide the number of dead bodies being removed from the tunnel, etc.
The CCP's policies on Hong Kong are also completely open. It just boils down to whether a person thinks the removal of democratic and civil rights is justified or not.
The biggest area of dispute is Xinjiang. In this particular instance the CCP totally denies genocide and is unlikely to ever say it committed it. However, it also has changed its story. Originally it denied there were any mass detention centres. When given the satellite evidence it said
"oh, those camps. No, they aren't detention camps, they're education and training centres with mass dormitaries and compulsory attendance".
Other parts of the CCP's policies are open, such as the stationing of non-Uighur CCP members in Uighur households, which does not appear to be a voluntary measure and happens whether Uighurs want it or not. Again, you may think it's a great idea, other people will say it's a gross breach of Uighurs' personal/human rights.
