"AIDS has more dollars-per-victim funding than any other major disease. Your disease is largely behavior-driven and preventable. You are getting more now than you have ever gotten, and you are still bitching about it. Y'know, I'll bet the diabetes foundation and cancer society would be grateful to get these funds. So since you aren't happy with what you are getting, I'm going to give the funds to medical causes that will appreciate it. F*** you".
(Of course this is cleaned up considerably from what I would REALLY say!)
Well, it's called the HIV/AIDS initiative, but actually also covers TB and Malaria (IIRC). IOW it's targeting the diseases that are having the major impact on human productivity in Africa and the Caribbean.
