"Now Dawkins does a wonderful analysis in his book The Selfish Gene, and again in later papers in more detail, of Roman Catholicism. As I'm sure you know he's pretty vehement about Roman Catholicism, largely because his daughter, when he split up from his wife was educated against his will in a Catholic nunnery and it must have been pretty painful for him to see this process happening. So he spells out what happens in Roman Catholicism."
From the Wikipedia article on Richard Dawkins:
He married Marian Stamp in 1967, but they divorced in 1984. Later that year, Dawkins married Eve Barham – with whom he had a daughter, Juliet Emma Dawkins in 1984 – but they, too, subsequently divorced. He married actress Lalla Ward in 1992.[4]
