A not small segment of the population still believes that man lived during the time of the dinosaurs. Some even still believe the sun revolves around the earth still. And you think that HIV transmission is the information the majority of people will be educated about?Are you kidding? HIV is not some obscure virus. It's one of the largest pandemics to hit the world in centuries. If someone doesn't know how it's transmitted by now they've either been living under a rock for the past 30 years, or they're being purposefully ignorant because they still falsely believe that it's a "gay" disease.
