Actually, I believe the Bible is protected by the same laws in Denmark that protect the Koran, namely, freedom of speech. The inequality that exists between Christianity and the other religions in Denmark does not give the Bible special status other than the fact that the state finances its publishing and the religion behind it.
The point here, Peter, is that the State of Denmark does not prohibit Islam. There are groups that, using various methods, try to do just that, however, but the applicable laws really are quite clear on this.
Islamophobics are everywhere, but thankfully, there is freedom of religion.
