Indigenous people would have recognized albinos as sickly, so that would have definitely been a concern. If ones accept Dr. Frances Cress Welsing’s albino theory, then to conclude that indigenous parents were being abusive when they quarantined or even abandoned sick ones (like albinos) is a misrepresentation of indigenous values.

It is highly possible that an indigenous community was ignorant of the cause of albinism and how to cure it. They perhaps thought it was infectious also. They could have felt that instead of risking infection to the entire community it was better to quarantine or even surrender the sick ones to nature/gods.

We have no evidence that indigenous parents were abusive and reckless. We do have evidence that they were caring and nurturing. I think it is incorrect to judge the (possible) action of isolating ones they thought had a communicable disease, so as not to contaminate the rest of the community, as an act of abuse.
