"The Vatican encourages sexual abstinence to fight the spread of the disease." I mean, yeah, abstinence is usually a really great way to a) not impregnate, and b) not spread STDs. However, I think that most of us understand that people are not always going to be abstinent. Nor should we expect that everyone be.
And this anti-condom view completely disregards women whose husbands are dallying on the side, then coming home and "spreading the love." Who is looking out for those women? And what about their children, who are exposed to HIV in utero? Doesn't the Vatican care about them? What about responsibility to others?
I would like the Vatican to show me RESEARCH that indicates that using condoms "increase" the problem of AIDS. Can they? No, because that research DOES NOT EXIST.
