Common sense and politically incorrect persons in epidemiology have been saying this since the first GRIDS was isolated and identified. It would have stopped a lot of pain and cost a helluva lot less. This is one disease that the genie got out of the bottle and political correctness and the disease amplifying population spread it with impunity. Politics has created the situation we are in, not the medical professionals that were interested in controlling disease.
You are assuming that there weren't any gay activists who wanted the disease to spread. After all, what's the good of being a "victim class" if one isn't the victim of something?
A key aspect of the liberal credo is that the more people do a wrong thing, the less wrong it becomes. There appear to be some people for whom this belief extends into diseases. They think that the more people have AIDS, the less bad it will be for the people who have it. While this belief is not completely devoid of foundation (after all, the more people have AIDS, the more money will be spent on research) it is morally bankrupt.
It's amazing how successfully the gay activists are able to blame everyone else for the AIDS crisis when it is they themselves who ensured its spread.
