The great replacement

I recently read that in the early part of the 17th century, there were twice as many people living in North America as there were in Europe.

That led to a further reflection — namely, the people who buy into the great replacement theory may be exhibiting a classic example of projection because they remember (subconsciously or consciously) that their ancestors did, in fact, engage in a great replacement. This was the replacement of the indigenous peoples of North America by white Europeans.
