I dunno, Steve. The whole Hitchens thing on Mother Teresa sounded like a conspiracy theory to me. Well, yes, she expanded her network of convents. I observed with my own eyes the work of nuns from two of her convents here in Northern California - the nuns devoted themselves to caring for the sick and the dying. They did good work, athough they were too conservative to be my cup of tea - and overly subservient to their leadership. But they worked hard to serve people in need, and those nuns have to be housed and supported somehow.
Here's a Guardian article by somebody who first disdained and later supported Mother Teresa:

But she's still not my cup of tea.
