You realize that list has events going back to the 1700’s, right?
If you want to talk about countries that have a pretty good go at being awful to fellow humans and we get to go that far back, I don’t think the UK would have an insignificant list.
It's kind of weird you felt the need to post this whataboutism three times in the same subthread, especially being that your main complaint is that the history is a complete history... I don't think this is the kind of behavior we want on HN.
