I have not once defended Osama's "interpretation" (he doesn't really have one-he's not a theologian)
It doesn't appear to me OBL has a religion of any kind, but he claims Islam (as do you), does he not? And he has committed, threatens and advocates cold blooded murder of innocent civilians in the name of Islam. And you, as a Muslim, do not disavow his claim to Islam (the same religion you claim), instead you excoriate the secular publication of cartoons equating his 'religion' with terrorist acts; when in fact he already tied the two together with his words and actions, using his 'religion' to justify his acts.
I really don't see what your problem is.
-but I don't think you know what OBL teaches in terms of religion anyway,
The entire WORLD knows what he teaches-violence and the murder of innocents along with the destruction of the western world.
