Being put under house arrest and prevented from having contact with the outside world by the government, without being charged with a crime is a pretty big abuse power. Imagine if Trump just put one of his critics under house arrest and prevented contact with the outside for several months. This would be an outrageous thing to do, and there'd probably have been riots outside the White House.
I appreciate you sharing your thoughts and I believe that you earnestly feel this is an okay thing for the CCP to do. But that's not swaying my skepticism and distrust of the Chinese government. The fact that it's successfully normalized this level of authoritarianism among mainland Chinese to such an extent that they earnestly see it as normal is precisely why most Westerners are so distrustful of the Chinese government.
