I recommend reading this Reddit post.

I mean, you do not refute the statement that "Teresa ran hospitals like prisons, particularly cruel and unhygienic prisons at that" by answering "oh they were not hospitals, just homes where the dying and destitute were housed without care".
You also do not refute the accusation that "mother Teresa withheld painkillers from the dying with the intent of making them suffer" by claiming that they didn't died on the street and those who did not died could eat a good meal and leave, or claiming that other hospitals on India were also not clean.
I stopped reading that nonsense. It is a wall of text where none of Hitchen's observations were refuted or addressed.
