I think part of it (not all but some of the reason) is that as a rule we simply don't possess a dominance based mindset or philosophy of living in the world. (I mean that a few of us have adopted this mindset in order to get ahead in this system but its not a general mindset among PoC.)

People who think like that simply do not understand that because that's how they operate, and its inconceivable to them that they could do the things they've done to any group of people and us not wanting revenge for any of it. (From what I've observed these people are well aware of the things their ancestors have done.)
