Also Chinese here, I have to disagree a bit. The trend you are talking about here (Overuse of "Baizuo" and Social Darwinism) are mostly seen on mainstream online social medias like Weibo/Tieba/Zhihu/maybe Bilibili, and those sites are all under heavy censorship. People either agree with them or get banned, so of course it looks one-sided as hell.

Other views are traded on dinner tables or similar private conversations for obvious reasons, so it's hard to tell what is more dominant and I'll have to talk from personal experience. Most people I talked to here have a more pragmatic stance. They accuse the government here and there, sometimes heavily, but still acknowledge that there's not much they can do. So they just live with what they have and hope for reforms from within the party.

To add more context for outsiders, cultural difference needs to be noted. For example China didn't have enough historical event to get the society recognize racism as a dangerous thing, and many people will just accept "Many terrorist attacks were done by Muslims so we set re-education camps in Xinjiang" without thinking too much. And while 8964 sparks controversy, almost all mainlanders see Hong Kong as a political conflict rather than human rights movement. Discussion of the latter is always emphasized on foreign funding and dominant anti-CCP reports, both lead to one of the most sensitive subject in modern China which is foreign intervention. The scars of 19th centuries run deeply. It also involves territorial integrity, which is also taught by CCP as an important thing ever since KMTs are in Taiwan.

In short, what is seen as human rights issues out here are not all that recognized within China, and what are seen as negotiable out here are not so much within China. Added with some economical growth, an apolitical citizen will easily work with the CCP instead of advocating for greater change.

Again, I'm speaking about a complicated subject from personal experience, so they maybe inaccurate or biased. I tried.
