Condoms are not needed if one simply abstains from intercourse before marriage and is monogamous during marriage. The Church proclaims the only 100% foolproof way of avoiding HIV (barring, of course, IV drug use or accidental needle-sticks by health care workers). This person simply doesn't like that this method requires that one keeps one's pants zipped.
Condoms prevent the spread of AIDS about as effectively as the use of the pill prevents abortion. The fallacy of his argument is that men will behave rationally when it comes to matters of sex. Distribute condoms widely and men will put them in their wallets, and KEEP them there. There is an element of magical thinking among the advocates of birth control methods. One good general health clinic in a country will do more to stop the spread of AIDS than a billion dollars spent on condoms and pills.
