This is pot / kettle black. It's not like none of this happens over here.

If you open a typical British or US history textbook, it omits or glances over most of the atrocious and dark parts of it's history.

As a result most population is unaware of their scale, or sometimes unaware of them at all. That's how you get false narratives in politics, usually nationalist ones. In my experience a typical brexit supporting person has never heard of half the stuff that was going on in the colonies.
