Europe sees itself as a liberal-minded society. It has no desire to be, nor can it be, a "Christian club.

Only a Europe that is conscious of its own values can be both an economically strong and a morally and intellectually respected partner, and thereby extend its hospitality to others. It's a cultural disgrace that we are forced to identify no-go areas for foreigners.

Christianity brought something new and revolutionary: freedom and unconditional dignity for each individual, regardless of his religion, culture or nationality. But the East and the West have parted ways since the Crusades.

Islam in the Arab world coexists with Indonesian, Pakistani and Turkish Islam. There is limited solidarity, even within the Arab world.

Europe's experiment with multiculturalism, or the side-by-side existence of different cultures, has failed throughout the continent. Integration requires a minimum basis of shared values, that is, a culture of mutual tolerance and respect - in other words, what constitutes the heart of European culture.

Islam developed in opposition to orthodox Christianity from the very start, and it considers itself superior to Christianity. So far, it has only been tolerant in places where it is in the minority.

The conflict with Islam has, after all, existed throughout European history.
