I read that San Francisco has launched serosorting. This is a loaded cannon. As an HIV+ man I find it hard enough to get a date, whether it's with someone who is poz or negative. The public still discriminates against those of us who are poz and this campaign is only going to encourage more discrimination.
The campaign is sending the wrong message in hopes of possibly preventing further infections. If you read between the lines, it is also saying that poz-poz dating is OK and not to worry about the so-called superinfection or re-infection theories.
