I was simply replying to the original statement that China doesn't kill protesters in the street. The notion is so risible that in hindsight it may well have been sarcasm or bait.

But, if you wish to expand the scope of this discussion, sure. There are several clear distinctions between the (horrible) events you list and what happened in Tiananmen Square.

The most obvious is that we are free to talk about them now. I submit that the Chinese state's continued censorship of the subject is a sign that (1) the state is still complicit in these crimes and (2) it is not "doing great".

The scale of brutality is also just incomparable. I say this fully agreeing the events you list were terrible. The horrors committed at Tiananmen Square were simply on another level.

ICE detention is already beginning to resemble the Salvadoran prison system.

Due process rights get violated. Detainees get shuttled around to different facilities to be lost in the system through engineered incompetence, making it difficult for legal counsel or family to find them, or even to know who has been taken. They subject them to torturous conditions, abuse, and often hold people who've committed no crimes for months.

They are thwarting oversight and defying court orders left and right. And they are trying to scale up like 10x+. And once they do, the detention system won't just be for immigrants. They are going to target anyone they want.

D's have successfully blocked DHS funding for now, but if they (or SCOTUS) allow any of this to go forward, things are likely to get far worse
