In China, you have no guarantees and no recourse. Torture, forced confession and retaliation against your family are all on the table.
That's why no one worries about US activists the same way they do about Chinese ones.
Such as moving those criminals and activists to Guantánamo Bay? Oh, Obama trolled to shut it down almost a decade ago after acknowledging its wide spread human right violations, why it is still in operation in the same shape and form? You are free to troll whatever you like, that is not going to change the fact that Guantánamo Bay is still being used for violating basic human rights.
liberal democracies? think about Guantánamo Bay.
Please stop spread your highly misleading non-sense. Let's don't even go down the paths of those weekly mass shootings in the US, when the constitution is basically denying their rights to live and the far right elements are calling for teachers to be armed on campus, what you can expect?
