And one thing about Christopher Hitchens, he hates Mother Theresa but he also denied the Holocaust. I don't consider him a credible source, as much as a journalist with an agenda. He hated all religion - esp. Catholicism.
There's a lot more to the Mother T story than what as shared but some of the criticism is valid. However, it's nonsensical to compare the quality provided at her hospices to Western Hospital standards.
(And these Western male doctors who criticized the nuns sure didn't stay too long in the slums to offer their expertise and make things better, did they?) It's easy to critcize, harder to put your $ where your mouth is.
