This was before the internet.
Black & White newspaper in Spanish about a convent/monastary that was being demolished and oops they found the bodies of both nuns and babies. Perhaps pregnant nuns?
I don’t remember.
There’s plenty of documented cases of it happening elsewhere, and you can call it libel if you wish.
Yes, you are correct: Since you are unable to provide hard documentation for any of it, libel is the only thing you could call it.
I am ashamed to see this kind of overt defamation crap on Free Republic.
