The colonization of Ireland may have been a model for future colonization projects but there is one key difference between what happened in Ireland than in India or America. The Irish were white, it doesn't matter if the racial scientists of the time proclaimed that the Irish were inferior to africans, in practice the Irish were treated better than any black person enslaved into chattel slavery. Oppression between whites has always been softer than white oppression of blacks, white and light skinned people throughout history have always been the oppressors no exception, they always own the most land, hold the prestigious positions, and are seen as the leaders. Black people do not think in terms of race unless forced to, whites do it naturally.
