Since the discovery of its aetiology three decades ago, HIV/AIDS has been an almost entirely preventable disease. Gay men and intravenous drug users (who account for almost all new infections in the US and UK) simply acting responsibly for once would have long marked it for eradication--at least in the developed world. That these people continue to infect themselves, even to the present day, is shameful, especially in light of the obscene amounts of money HIV research diverts from worthier causes, such as pediatric cancer or Alzheimer's.
These people are not heroes and deserve to be shamed at least as much as oxygen tank-toting chain smokers who gave themselves Emphysema.
