German butchers who sell pork are targeted by Muslim extremists, according to Ulfkotte. Muslims occasionally spit on sausages on sale at open-air markets.

In some European cities Muslim taxi drivers refuse to transport dogs, even blind persons with guide dogs. Two schools in Berlin have installed two separate entrances – one for German Christians and Jews and the other for Muslim Arabs and Turks.

The Muslim Sharia law is also beginning to take hold. Banks are offering Sharia-friendly investments, Ulfkotte said. Authorities in Berlin have recognized a Sharia lawyer, who settles family feuds.

According to the journalist many German politicians turn a blind eye to the gradual Islamization. They often emphasize that the vast majority of the 3.5 million Muslims in Germany are peaceful citizens. But, says Ulfkotte, 40 percent are convinced that the German constitution is incompatible with Islam.

According to the journalist many Muslims in Europe show a lack of tolerance. For their integration to be successful they would have to adapt to basic European values.

Hindus, Ulfkotte said, are a good example that this is possible. They accept that Europeans eat beef, although Hindus regard cows as sacred animals.
