The solution isn't perfect, therefore nobody should use it.
But less than 100% protection can be a problem, if it's compensated by people engaging in riskier behaviour. If without condom you wouldn't go screw the first prostitute in sight, but with condoms you do, then effectively condoms have increased the risk of contamination.
This is already well documented in other domains.
E.g., people who bought cars with ABS actually end up having more accidents on the average, because they believe it to be better than it actually is, and drive riskier. E.g., closer to the car in front than someone who knows he doesn't have ABS.
E.g., wearing bicycle helmets actually caused people to have more and worse accidents, partially for their own increased recklessness and partially because drivers seem to come on the average a whole 3 inches closer to someone wearing a helmet. You know, oh, he has a helmet, it's not as bad if you accidentally bump your car into him.
There is even a hypothesized Peltzman Effect where each safety measure or regulation is compensated, or sometimes more than compensated, by people acting riskier than without it.
Which is really the core of the Pope's argument.
According to the OP he's saying more than that: he's saying that abstinence education leads to fewer cases of AIDS than does promoting the use of condoms, at least in Africa.
That, to me at least, is surprising, and I had thought the opposite was true.

Main article: Sexual violence in the Democratic Republic of the Congo
In eastern Congo, the prevalence and intensity of rape and other sexual violence is described as the worst in the world.[79] It is estimated that there are as many as 200,000 surviving rape victims living in the Democratic Republic of the Congo today.[40][41] War rape in the Democratic Republic of Congo has frequently been described as a "weapon of war" by commentators. Louise Nzigire, a local social worker, states that “this violence was designed to exterminate the population.” Nzigire observes that rape has been a "cheap, simple weapon for all parties in the war, more easily obtainable than bullets or bombs."
South Africa
Main article: Sexual violence in South Africa
It is estimated that a woman born in South Africa has a greater chance of being raped than learning how to read.[80] One in three of the 4,000 women questioned by the Community of Information, Empowerment and Transparency said they had been raped in the past year.[81] A survey conducted among 1,500 schoolchildren in the Soweto township, a quarter of all the boys interviewed said that 'jackrolling', a term for gang rape, was fun.[81] More than 25% of South African men questioned in a survey admitted to raping someone; of those, nearly half said they had raped more than one person, according to a new study conducted by the Medical Research Council (MRC).[82][83] It is estimated that 500,000 rapes are committed annually in South Africa.[84]
http://news.bbc.co.uk/1/hi/world/africa/1703595.stmRape, including child rape, is increasing at shocking rates in South Africa. Sexual violence against children, including the raping of infants, has increased 400% over the past decade (Dempster, 2002). According to a report by BBC news, a female born in South Africa has a greater chance of being raped in her lifetime than learning how to read (Dempster, 2002). When South Africa became a democracy in 1994, there were already 18,801 cases of rape per year, but by 2001 there were 24,892 (Dempster, 2002). Numbers vary by different institutions, but are nevertheless extremely troubling. The Institute of Race Relations found that more than 52,000 rapes were reported in 2000, and 40% of the victims were under age 18 (du Venage, 2002). The University of South Africa reports that 1 million women and children are raped there each year (South Africa: Focus on the Virgin Myth, 2002).
High Profile Baby Rapes
A number of high profile baby rapes since 2001 (including the fact that they required extensive reconstructive surgery to rebuild urinary, genital, abdominal, or tracheal systems) increased the need to address the problem socially and legally. In 2001, a 9-month-old baby was raped by six men, aged between 24 and 66, after the infant had been left unattended by her teenage mother. A 4-year-old girl died after being raped by her father. A 14-month-old girl was raped by her two uncles. In February 2002, an 8-month-old infant was reportedly gang raped by four men. One has been charged (McGreal, 2001). The infant has required extensive reconstructive surgery. The 8-month-old infant's injuries were so extensive, increased attention on prosecution has occurred.
It is also trying to dispel a widespread rumour - that having sex with a virgin cures Aids.
Traditional healers, or witchdoctors, are blamed for spreading this idea, and encouraging child rape.
A sociologist, Lisa Vetton, draws a parallel with Europe, when child prostitution was rampant
"At that time venereal disease like Aids today was incurable. If you had gonorrhea or syphilis you were going to die. And exactly the same myth emerged, that sex with a virgin is going to cure you - so it seems like a very old response whenever sex and death are combined. Suddenly women - girls - get attributed with magical healing powers".
I just don't get cultures which treat women so badly, whether we're talking about South Africa or Russia or Saudi Arabia. And obviously, these kinds of attitudes were a lot more prevalent world wide in different time periods. I mean, don't these men have mothers?
Not that it's only men who promote abuse against women. Some of the biggest supporters of female genital mutilation, even the most extreme forms of it, are the mothers who wish to do this to their daughters. It's often the mothers and grandmothers who perform the circumcisions.
They do. Who do you think teaches them to put the wife in her place?
Let's just make sure we understand that the Vatican ban on condoms is not based on the view that condom education is ineffective at creating optimal use, but on very bad science and outright lies about condoms.
Has anyone ever said that abstinence isn't the most effective method of preventing transmission of an STD?
Well I was more talking about the massive issue with rape and sexual violence aspect of it (as in Marduk's examples) when I said the "Don't these men have mothers," as opposed to treatment of women in the home, which, as you said, can be learned from one's mother as much as one's father, in some cases even more so.
In interviews and her memoirs, Ayaan Ali Hirsi talks about the fact that her father was away much of the time, and he had a less strict attitude towards women. It was her mother and grandmother who raised her, who performed FGM on her, who beat her when she didn't act like a completely submissive woman.
