Excerpt:
A poster campaign by Germany's Interior Ministry to advertise a hotline for those worried that a friend or family member may be turning to radical Islam has incensed some Muslims who say it stigmatizes them.
Germany, home to four million Muslims, has become increasingly concerned about home-grown Islamic militants over the past decade after Hamburg served as a base for three of the September 11 suicide airline hijackers in 2001.
Officials are especially worried about the ease with which individuals can be recruited over the Internet by extremists. Last year a young Kosovo Albanian Muslim shot dead two U.S. airmen at Frankfurt airport after being radicalized online.
