In the case of Irish indentured servants, I’m sure the difference between them and enslaved peoples from Africa were only academic from their perspective. And there is so much that I don’t understand in terms of the circumstances of them leaving Ireland. However with respect to the institutions that have developed since, equating the two requires a narrow analysis of the scale (numbers and time) and permanence (legal and cultural) of both. Hence the importance of understanding the facts of your own background in order to have healthy exchanges with people of different backgrounds (especially when historical, violent oppression is involved).
Edit: I should add and also excepting that others may have deeper understanding and taking a posture of learning instead of “winning” from the exchange.
