Some might find them threatening, I find then to be signs of mental disorder. And philosophical justification for his own hatred.
I find what he says as threatening, especially after seeing what actions he and AQ have taken around the world. They are not only manifestations of a mental disorder, they are the musings of a murderer. His followers are willing to fly planes into buildings and commit murder using bombs strapped to their bodies and in their cars. I take what UBL says very seriously.
But I will not get bent out of shape over his musings.
He, and every one who follows him will die.
There is no question about the end result.
I am puzzled why you are pressing this point. His justification is philosophical and seriously flawed. And it will be his demise and perhaps the demise of his religion (as we know it) as well.
