There is no such thing as natives, really. Well, maybe only in the Congo river basin – according to this map.
We all are migrants. There is no reason to be hostile to newcomers or to kick anybody from the land they live on. Tribes are coming and going, splitting and merging. Saying “My ancestors always lived here” is misleading. The only pride we can take is in being kind to each other here and now, it has nothing to do with ancestry.
