Is China really that bad?

Now talk to Chinese expatriates who fled the communist nation for freedom in the United States whereupon you will discover from them that the answer is 'yes' China is just that bad.

When Wang Weiheng fled to the US,the CCP let him be,then he joined some illegal Mexican immigrants in their journey to the US and got backstabbed by them,when he entered the US,his money is no longer a thing and he got sent to an immigrant detention center for 6 months,after he was released,he continues to praise the US for "freedom" and doughnuts with the latter quote becoming a meme back in Chinese borders,when he finally decided to get a j0b which is delivering takeaways,he twisted his hip,he was then asked to pay when he told the doctor about what happened(He mixed up the US and Canada.)which made him angry and he started to hate BOTH the US and China,in the present,he was on a hiatus for at least 6 months and someone leaked a picture of him missing one eye(Likely caused by beatings.)

And then without cherry-picking there are thousands -- perhaps tens of thousands -- of expat Chinese who are extremely happy with life inside the United States.

That's no longer the case because the US is now arresting immigrants left and right

Not the ones who immigrated legally; and this includes expat Chinese who went through the legal process.

Even legal immigrants and those that descended from immigrants are being arrested now.

No they are not . . . unless they advocate for harming the United States. Their visas TELL them that they cannot do that.

Because the US want to use them as propaganda tools

Translation . . . all your rationalizations have been methodically debunked.
