There's a bit of a difference between the likes of Britain, France, the Netherlands, Portugal, etc, who committed atrocities primarily in the days of colonialsm and have since drastically changed — they've acknowledged what they've done, and to my knowledge apologised for it — and China.

China hasn't become less authoritarian since the massacre, doesn't acknowledge it even happened, and certainly hasn't apologised. The sad truth is, they'd likely do it all over again. Because they're just as bad now as they were then.

I hate the "but whatabout..." whenever someone calls out China on murdering their civilians and even committing an ongoing genocide.

If you actually think China and nations such as Britain, Canada, France, Spain, Germany, etc are the same, you frankly need to get your head examined.
