I know that for some people, staying private about their HIV status is a matter of personal safety. But I believe a lot more people could be open about it, and their only reason for not doing so is fear. That's a powerful emotion, but fear doesn't excuse us for standing by as others are stigmatized.
I am embarrassed to admit that until June 27, 2013, I used "I'm HIV-negative" as a substitution for "I haven't been tested." Whereas I did not know my HIV status and could have been positive, I rejected William, a person who did the responsible thing by getting tested and telling me about his status.
