So you are willing to have your head hacked off by these lunatics so you can be a blip on their vile internet site and on Al Jazeera. I prefer to be ALIVE to fight and destroy these evil, evil men who are an affront to the Judeo-Christian ethic and to all decent people. You beat them by staying alive.
If I had to rate my preferences, having my head hacked off would a distant third behind 1) stomping these vermin into the dirt and living happily ever after and 2) taking a few along with me.
