A big argument I see by Chinese nationalists online, which I think carries validity, is that Western governments who enshrine human rights and democracy in their constitutions throw their weight behind horrific dictators that support their business interests and suppress democratic movements that don't.
Basically, Western governments aren't more moral than China; just more constrained by our institutions.
Regarding the lack of good samaritanism in China, this is a recent thing stemming from a 2000s legal case where a man was sued after taking an injured girl to hospital. Most Chinese, especially the older ones, find this aspect of their culture abhorrent and there are active campaigns against it in several cities.
Meanwhile it's undeniable that Taoism is a major cultural cornerstone of China and very much affects how the state and its population are related. Thus "Moral relativism is a cancer, applied selectively by the lazy. Do better." is actually quite an ignorant statement that applies a specific moral lens to the entire world without acknowledging the lack of universality in ideals across humanity.
The existence of other frameworks of morality doesn't mean that there isn't one True Morality. It just means that some people act against it.
Probably not, because anything human will only be an approximation. It's probably a whole damn closer than the Chinese morality though.
> To suggest that there's somehow a single philosophy that's correct is quite pompous. Why? In science we accept that there's one true way that any process can be described. Others might be entirely wrong (theory of Humors), or partially wrong, but useful (Newtonian physics). Why is the notion that there's on true moral framework so outlandish?
It's not pompous, it's reasonable, as in it's a deduction that anyone can make for themselves with the reason they have, applied to the vessel they were born with.
That doesn't mean one isn't morally right and one isn't morally wrong.
If you want a hint for which one is which: one asserts that every living person has basic human rights. The other has frequent videos of people ignoring people who are dying, are currently destroying an indigenous population in concentration camps, and when a novel virus broke out, first shut up scientists trying to get the news out, then underplayed it, and then as it started spreading saw citizens weld shut doors of people suspected of having that virus.
