I don't think it was meant to put a positive (no pun intended) spin on having HIV because I imagine 95% (if not more) of those who are infected wish they weren't. And one of the main reasons for that is the social stigma that comes along with having HIV. The gay community is already pretty small and then when you have something like HIV it becomes that much smaller. Sure, most people won't care if one of their friends is positive. I mean, it's sad to see what they have to do and it's a reminder (hopefully) to protect yourself. However, for a positive (often referred to as 'poz' in slang) to date it's much harder. Very few people would risk a relationship with someone who's positive because they don't want to risk contracting the disease themselves. Therefore, HIV-positive people have to, in a sense, seek out other positive people for dating and relationships. I don't think gay.com, of all places, would be glorifying HIV and being positive. While I don't necessarily agree with all that gay.com does I do know that they would not exist if they actually supported such issues. The fact is, despite being relatively small, they gay community is spread across the economic and social disapora. You can't lump us into one set group because there will always be those that break the mould. Organizations like gay.com try and act as a bridge to bring us together by trying to put attention on all aspects of gay life...one of which is being HIV-positive. I don't think they were trying to put a spin on being positive like "Hey, we're positive! Look how fabulous it is!" but rather "Hey, I'm positive and so aren't my friends here and we just want to show people that being positive is not a death sentence (though I will one day die from it) and, if possible, I'd like to meet other positive people".
But, I think it this shows exactly what gay.com does. It has shown ConcordeBoy that there are other facets of gay life other than the clubby twinks, the pretty A&F crowd, the S&M crowd, and other "mainstream", visible groups. People often have the misconception that being gay you have to be this way or that way (which, gay or straight, is true to a certain extent) but that there are also groups of people, through extenuating circumstances, may fit into one of those groups but may also fit into others as well.
