I just can't stomach the American Red Cross. They lied and killed people during the early AIDS years, they drive up the price of blood by selling it to brokers, they take money for causes and spend it how they wish, and they charged my grandfather for coffee during the First World War. BLEAH.
Thanks to rroseselavyoui for the list of donation possibilities. I actually went direct to habitat.org because I figured that site probably shaved a bit off the top.
