Because there's no point in trying to contest China, especially when most controversies over them are just them handling their internal affairs. Many western governments are very warm with China, western corporations love the cheap labor that china provides, china is already the world's number one trade partner, they'll be the number one economy within a generation, etc.
Going on the internet and saying "grrrr, I dislike china" isn't going to change any of this, and keeping your hand in the sand pretending china isn't on the raise isn't going to stop it either.
China is raising while the West is failing, whatever china is doing is working for them, while what the west is doing isn't.
Also don't forget, the world hates the west far more for their treatment of blacks and muslims than the world hates china for its treatment of its minorities.
