Oddly enough, people seem to have lost their fear of AIDS. Sure, there are drugs that can fight the virus and extend the life of someone with AIDS; but if they stop taking the drugs, AIDS remains a fatal disease. You’d *think* that people would keep this in mind and behave accordingly, but you’d be wrong. There are some drugs that can be used as “pre-exposure prophylaxis (PrEP),” meant to protect you from getting HIV in the first place; and while they seem to be largely effective, they are not *completely* effective. Behold:

PrEP Fails in Gay Man Adhering to Daily Truvada, He Contracts Drug-Resistant HIV

To me, these drugs are somewhat akin to carrying a concealed firearm. Such a firearm, if you are an intelligent, sane person, is there to protect you in case something unexpected occurs. Someone undergoes Sudden Jihad Syndrome at the Piggly Wiggly, for instance, and you need the gun to defend your life. You know what that pocket pistol *isn’t* good for? Intentionally launching yourself into gang territory to find the local warlord and challenge him to a duel. Similarly… if you don’t want to get AIDS, you really shouldn’t have sex with people who have AIDS. Even if you are taking some drugs.
