It would be good to have as much vehemence for any of the many situations that is the legacy of colonial mentality. It may be easy to declare distance from history, but when that history has clear impact on present day actions, it is very much a part of the present. Do we sit and allow prejudicial and racist activities (i.e., Indigenous continuing to lose their lands, is but one example) because 'I'm not that government, corporation, neighbor' doing it? We'll just let the attitudes that have systematically made themselves part of our societies, our laws, our economies, etc., exist since those things have nothing to do with us who are somehow not part of history, not part of the legacy.
