The Catholic Church is telling people in countries stricken by Aids not to use condoms because they have tiny holes in them through which the HIV virus can pass - potentially exposing thousands of people to risk.
The church is making the claims across four continents despite a widespread scientific consensus that condoms are impermeable to the HIV virus.
A senior Vatican spokesman backs the claims about permeable condoms, despite assurances by the World Health Organisation that they are untrue.
I am not going to try and pick holes in the Vatican's argument. They only took 300 years to admit they were wrong about Galileo.
Pity that this scientific error, unlike the geocentric theory of the universe, will kill people.
