well, old Marx already knew that 150 years ago

However indeed an interesting interview and one of the religious persons who has some views which I as an agnostic can support. Of course he also gets threats from radicals

In this interview (available only in german)
http://www.heise.de/tp/r4/artikel/32/32217/1.html he states that he considers the spiritual side of islam as timeless as well as he says that the "earthly-juristic" side belongs into the 7th century and has nothing to lose in the 21st century.
