You might have a semblance of a point if you ignored everything else about this event, including the other things he said and the person he targeted.
In my mind, those hold far more weight than a sentence he said. But you're just seeing what you want in this (confirmation bias).
Ah yes, I might have a semblance...
Your argument revolves around political motivations. The same political motivations that are part of EVERY terrorist attack. You somehow,
in your mind, find a way to rationalize this persons step up to killing. By your logic, nobody is a terrorist, as long as they have political motivations. Or maybe motivations you agree with.
Is this a direct self defense killing? A crime of passion? A bout of mental illness? A premeditated act of hate?
Why did he think he had the RIGHT and AUTHORITY to kill someone?
We are the ones who pledged allegiance to Mohammed, to wage jihad.
Besides his words, he further affirms his ideology with the 1 finger salute as well.
Most people have rational political motivations to disagree with events, but they do not resort to killing people. This person used his religion as a mental and psychological vehicle to kill someone.
