Look up patient zero. He was as gay as they come.
He was pretty gay for sure, but he was not, in fact, patient zero. Yes, he was involved in the early spread of the disease in America. By the time he was discovered, though, the virus was well-established in the US population. People were quite unaware of the long asymptomatic period of HIV. His role in the spread of the virus is pretty insignificant in comparison to its spread through heterosexual communities. People travel, get a little something on the side, and bring it back to their wife or ladyfriends in their country of origin.
It was an African disease, yes. And it would've stayed that way.
Even if nobody was taking it up the pooper, HIV would have still spread worldwide. Different demographics would have been the first struck in the West. HIV was all but destined to become a pandemic, though. As far as viruses go, this one is exquisitely adapted to spread among humans. It has a very long asymptomatic period during which transmission can occur. It emerged in a neglected part of the world and spread there extensively. On top of that, HIV was a hard virus to "discover" since its most noticible symptom is immunosuppression.
But no, your gays spread it to Namerika and then Namerika gave the gift to the rest of the world.
You've got it a bit out of order. HIV had been spreading in Africa for a long time before it reached the US. When it reached the US, it struck the gay population, but the gay population played a minimal role in the worldwide spread of the disease.
Some rules are for the greater good.
And some are pointless anachronisms that fly in the face of human nature. People are horny and promiscuous, regardless of their orientation. No amount of pontification will change this. Sexually transmitted diseases have historically been some of the most successful human pathogens despite a bunch of religious claptrap about "sexual purity". There is a reason for that. My advice - keep it to one woman at a time and wear a rubber no matter who you're fucking, unless it's your wife and you know she's clean.
None of MY "superstitions" have ever been harmful to me or to those I know. My "superstitions" might be harmful to YOU, but that's quite another story.
The fact that your superstitions are harmful to anyone should give you cause to question their legitimacy. They're superstitions, for fuck's sake... human contrivances that serve no purpose other than to spread themselves. Much like a virus.
As far as them being harmful to me, I'm not sure what you mean.
