Your first quotation is not about someone excusing a genocide because it happened a long time ago. They are saying that unlike the US, the current inhabitants in those regions can be traced back to the inhabitants thousands of years ago. Which means there wasn’t a major genocide or displacement of people. I am not endorsing this statement btw, I don’t know enough to confirm it. But it is not a condonation of genocide. It is in fact remarking that a genocide similar to what happened in North America did not happen in those other regions.
As you also wanted to be pointed to a source for genocides on the same or larger scale throughout history
You provided me a list of genocides on Wikipedia. None of them match the genocide against native Americans. Your link proves my point.
I guess I need to spell it out for some
I didn’t ask you to paraphrase or restate your point. I asked you to prove it or provide evidence. But I never expected you to be able to anyways, so don’t worry about it.
