Every argument you have given so far educating people in preventing AIDS is futile, because behavior isn't a factor.
Huh? Education is all about behavior. You teach people what behaviors expose you to the disease and which don't.
Monogamy = good.
Unprotected sex with prostitutes in sub-Saharan Africa = probably not so good.
That may seem like common sense, but in an area where many people lack even basic education, and where lots of myths abound, that message isn't always getting through.
