After the bombings in London, I saw a picture of a large group of young Muslim men in London praying outside in their neighborhood. It triggered some thoughts about secularism.
Modern Europe has pretty much eliminated Christianity from the public square and established secularism instead. So it's very ironic that religion is coming back with a vengeance, but in this case the religion is Islam. Secularists thought they had gotten rid of the--to them--evil demon of religion. But for various reasons the rise of Islam in Europe is a very real phenomenon. Right now, Mohammed is the most popular name for newborns in Europe. And when the Islamic population reaches a critical mass, they will not want to live in a secular society but in a religious one, that is, an Islamic one.
I don't know how this will all play out, the bombings in London now are only the beginning. Think about the irony, though, that in England for many years after the Reformation it was illegal to be a Catholic. Catholics were persecuted and had no freedom of religion. What would those Englishmen have thought if they had known that their descendants would be living in an Islamic country?
