Not a lot of intelligence is required to deduce that the HIV virus is something one does not want to get. It is survivable, perhaps---with money and a great deal of effort and inconvenience, but it is highly undesirable, both for the individual and society. Probably hundreds of thousands of dollars are lost for every new HIV patient.
The main reason the gay community was and still remains a favorite target of the HIV virus is due to the ancient and traditional practice of anal sex. Therefore, any intelligent and self-respecting gay must refrain from anal intercourse, even with a condom, even with a supposedly monogamous partner. This seemed obvious to me back in the day and remains so. Abstinence is best for gays, regarding that one act, although everything else remains on the table. This is a sacrifice that must be made by any living gay today that wants to keep on living and pursue serious goals. On the one hand, it may seem a humiliating concession to the misguided fundamentalist Christians, but so what? Survival trumps meaningless pride. Science cannot be defied by the wise. The A will be back again when an HIV vaccine gets mass-produced.
There was a case in the U.K. recently involving a sociopath that intentionally infected other gay men, then taunted them with the fact afterward. This insect is by no means the first and will not be the last. He deserves death, swift and soon, but was instead sentenced to a lengthy imprisonment, owing to the U.K.'s ineffective legal system that coddles criminals and saddles their taxpayer with enormous costs, that murderers might pick their noses for many decades. At any rate, there are some men that will infect others intentionally, out of malice, because they are wicked spirits. There are some that will do so out of negligence, because they are fools. There are some that will do so due to pure blind chance, because no condom will ever be entirely effective in all cases, no matter what. For all of these reasons, the A is out.
