HIV/AIDS is still a fearsome disease, even if there are increasingly effective treatments for it. Much of the stigma is rooted in false beliefs, but I think it's irresponsible for people to call the fear of HIV/AIDS illogical. HAART treatments cost thousands of dollars, and I doubt there'd be a cure for the next 5 to 10 years. We might figure out what is necessary for a cure, but then we'd have to initiate clinical trials and those take time. According to various internet sources, it takes about 10-15 years for a drug to go from discovery to market. Even if we did develop a drug, let alone decipher the biological mechanism behind a potential cure, in 5 years, it'd still be 2030 before you have a cure that can be delivered to patients. I'm all for eliminating the stigma, and placing society in a position where it doesn't have to fear HIV/AIDS, but I don't believe in false hope.
As for educating people, I'm a bit pessimistic. I believe this issue was more of a hot topic around 5-10 years ago, but maybe that's just me. Personally, I think the cause has lost ground to other social justice issues in the public attention span. Rape is popular, feminism might kinda be popular? LGBT representation in the media is popular, but I haven't heard anybody talk about HIV/AIDS lately.
