I just sent a letter to Kiva.org.
I was about to make a loan when someone pointed out
this borrower. I can't believe you allow support of this "business." Not only is it a barbarian, violent, and incredibly inhumane sport, it's gambling. It's not supportive to third world economies to support gambling and violence, perpetuating patterns that are destructive in nature.
I won't be using Kiva for my donations and support work.
