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

The religious wars showed that the Christian faith was no longer Europe's unifying force. A new common ground was needed, and it was found in reason, which is something that is shared by all of mankind. This was one of the roots of the Enlightenment and its concept of universal human rights.

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.

Where it is the majority religion, Islam does not recognize religious freedom, at least not as we understand it. Islam is a different culture. This doesn't mean that it's an inferior culture, but it is a culture that has yet to connect with the positive sides of our modern Western culture: religious freedom, human rights and equal rights for women.

The end of World War I also marked the end of bourgeois culture. An inner emptiness developed that, in the 19th and 20th centuries, paved the way for two ideologies that dragged Europe and the world into an abyss and plunged it into a catastrophe.

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.

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