At LAST, you ask an INTELLIGENT question! At LAST!
I don't know the answer to why AIDS gets so much more attention and funding and political capital than far more virulent and easily communicable diseases.
If you ever find out why AIDS is so much more important, let us all know.
The diseases I mentioned were mesothelioma, lung cancer, and heart disease. Which of those, exactly, is far more virulent and easily communicable than HIV/AIDS?
