And the world is flat:

The lives of Roman Catholics in some of the countries worst hit by HIV/AIDS are being put at even greater risk by advice from their churches that the use of condoms does not prevent transmission of the disease, according to a British television program. If condoms cannot be absolutely guaranteed to block sperm, they stand even less chance of stopping the much smaller virus, the churches' argument runs.

The Archbishop of Nairobi, Raphael Ndingi Nzeki told the program: 'AIDS...has grown so fast because of the availability of condoms'
