They were indigenous children found in deep graves at the schools they were sent to in order to convert them from their beliefs to Christianity. They were in supposedly “Christian” schools. It is another horrific case of evil being carried out in the name of Christianity. Sadly, the Christian faith will bear the brunt of this crime rather than the evil behind it.
The school was there for some 200 years, and prior to the discovery of antibiotics, infant and child mortality was enormous. I am involved with an historic cemetery that closed at the end of the 19th century and we have a huge number of children buried there, certainly by today’s standards.
Remember, even measles was a deadly disease in those days, in addition, of course, to diphtheria, whooping cough and the bane of institutions, tuberculosis. And any cut or burn that became infected was also dependent entirely on the strength of the individual to resist the infection, since there was literally nothing else.
I know you may hate Christianity, but this is not something you can blame on it.
But the thing is how is it “news”. They went LOOKING for these dead kids, so someone or many people already knew about it.
