Germany is beginning to experience the British and French malaise of homegrown Muslim radicalism, as a Muslim subculture becomes more entrenched.  

In this subculture. European converts and second-generation Muslim immigrants to Germany mix together. The converts and many members of the second generation do not have a command of the native tongue of the first generation immigrants, leading the Islamists to preaching to them in German rather than Arabic, Turkish or Pashto. Moreover, as reported by Reuters, the preachers are not confining themselves to the mosques but are taking a more public approach to proselytize.

Sheikh Abu Adam of the the Darul Quran Mosque in Munich, recently lectured at the city's Catholic University about "An Islam which distances itself from violence" The sheikh forgot that when he broke the nose and shoulder of his wife and mother to ten of his children (he has two other wives despite the German law) when she asked to live a more westernized life.

Former boxer Pierre Vogel, who converted to Islam and studied in Saudi Arabia, is now an Islamic preacher who rails against Muslim integration into German society. Denis Mamadou Cuspert, originally from Ghana, is a former rapper called Deso Dogg. He turned from rap to Muslim religious chants with the common theme that Islam is under attack from the West.

Radical Islam has given respectability to people who were on the fringes of society, including former convicts.

The preachers are augmented by German language Internet propaganda that forms a virtual group and can help serve as an incubator for Islamic radicalism. The 21 year old Kosovar who murdered American servicemen claimed at his trial that he was influenced by the Islamic internet messages that, in retrospect, he knows were false.

Another important component of the Islamic subculture in Germany are the arbitrators,  local and occasionally flown in from Turkey and Lebanon who have established a parallel legal system bypassing the state.

Der Spiegel quotes one juvenile court judge who charges: "The law is slipping out of our hands. It's moving to the streets, or into a parallel system where an imam or another representative of the Koran determines what must be done." 

Arbitration is a respected practice, particularly in financial matters, that helps keep the courts from being swamped. Islamic arbitration however is now competing with the criminal justice system and taking crimes of violence out of the hands of the state, while engendering distrust for the established legal system. Such alienation also breeds radicalism.

The German tabloid Bild quoted German interior minister Hans Pieter Friedrich saying that there were 1000 potential Islamic terrorists in Germany including 128 whom the authorities classify as very dangerous. 20 of these have attended terrorist training camps with Pakistan the preferred destination..
