They were initially set up in good faith - if we ignore that its just another tool for indoctrination, sure. And if the nuns etc hadn’t set up those schools and buried all those children in the grounds, then the soil there would be less fertile.

Faith can be good for people. But so can truth and evidence and fact, so maybe we should focus on those things that are real.

All forms of religion are absolutely indefensible in this day and age.
