Leaving Islam for Catholicism in France
Ibn Warraq ed. Apostates of Islam, p 99:
“Even in the West, Muslim apostates fear for their lives and find it difficult to come out in public; hence the difficulty in finding reliable statistics for conversions in the West. However, we do have some figures for adult baptisms in French Catholic parishes. The latter parishes also record the religion of origin of those baptized. In the year 2000, 2,503 adults were baptized of which 9% were of Muslim origin; thus 225 apostasized in France alone in 2000.”
AD says: it's something, but don't get all excited. Many more nominal Christians become Muslim in a given year than the other way around, at least in France.
