to suggest we have “just as dubious morals” as China is categorically wrong.

Only if you have a wilfully short memory and/or are wilfully ignorant of the atrocities that came with far reaching British imperialism (never mind completely ignoring the news, we have camps, hundreds of asylum seeking children disappearing, disabled people being quietly killed off, trans people having their rights removed and so on and so forth never mind the "run of the mill" systemic racism sexism queerphobia ableism classism and so on, and pretending these aren't all active stages of fascism is helping normalise it)

With the internet at your fingertips there is no excuse:
