I want to mention, people whose family were dragged through the culture revolution, etc., CAN have legitimate concerns and trauma. They aren't just wrong, things WERE scary.

My grandparents on both sides had ran away from their farmer families in their teens to join the Long March, eventually all made contributions to the Party (e.g. once, my grandma served as a spy behind Japanese lines in a village, then when she had to escape back to safer grounds, traveling outside hiding in sheds in winter, wearing just a shirt, she'd lost her baby to miscarriage). They all attained fairly high ranks, were known to have done exemplary work. During the culture revolution, they were accused of being far Right for various quite often arbitrary reasons. My grandfather's family had been farmers who owned a few small pieces of land (5 mu), and even though he had ran away at 19 and never went back, he was deemed bourgeoisie no matter what he'd accomplished. They locked him in a dark cow shed for 2 years, with handcuffs so tight the scars went to his wristbone, and his kids were allowed to visit once per month. My other grandparents had similar stories. Some years later, all of them were released, reinstated. Some received formal apologies from the Party.

My parents grew up during the Culture revolution. They witnessed their parents in various stages of lock up, but were still full of fervor, voluntarily went to the rural villages among the first wave of educated youth following Mao's call, and neither were granted party affiliation due to "tainted family background." Years later, this continued to pop in random ways, subverting their career trajectory. This was through to the end of the 80s to early 90s.

My grandparents remained loyal to the Party until they died. They forgave the bad stuff. But if they didn't, if other members of my family had differing thoughts and feelings as result, those are a legitimate response to what had happened. They're part of the complex history of new China. There are people who are alive now who still have memories. Sometimes, when the repression gets higher, even for seemingly legitimate reasons, some people have ptsd.

The CPC isn't an angel, and it made mistakes and people got hurt. The difference is, if we want to discuss material conditions, we should probably focus on: has the CPC changed since that time? Has it improved the lot of the Chinese people? Does it clearly demonstrate that it intends to continue to serve the interests of the people, promote equality and common prosperity and all the good things? So long as these remain true, the CPC is worthy to be supported, and held to high account. And not by pretending terrible things didn't happen either, or that 60 years is all that long ago and everyone should all be fine now.
