Because a lot of people don't like fags and the disgusting sexual practices that they practice which just so happen to cause them to catch this kind of filthy disease.
Ok so let me get this straight. You don't like American homosexuals, so you want 40 million people, a large majority of whom aren't homosexuals but who are infected with the same disease that many American homosexuals have, to die? Am I missing the logical connection there? Because that doesn't seem to make too much sense to me.
I don't get what a Zulu in South Africa, a Kalanga in Botswana or a Chewa in Malawi have to do with a Liberace in the States other than the fact that their infections look similar in a lab. But again, maybe I'm missing something.
