In broad strokes, I had visualized that scene before you posted the link.
I need you to understand the depths of the rage that overpowers me every time something like this happens and gets thrust into my attention. It's immensely worse than what I feel even during school shootings here. Because this is something else. This is a faction of humanity with no soul, no respect for life, no honor, and no purpose other than to destroy the bright future of the human race. They are worse than the Borg. The Borg are unfeeling, following a cybernetic mandate. Islamic Jihad, in its modern incarnation, is pure hatred, and pure evil. They want no discourse. They want no appeasement (which never works anyway). They don't want to be left alone. They want to assimilate, and destroy everything that they cannot have.
Like the Borg, who deserve it less, the only solutions are total confinement or total annihilation. Total at any cost. I've said this before, and I will say it again: It's in the best longterm interest of everyone to work toward this, particularly those who share a place and a culture with them. Sooner or later, someone just as enraged as I am will get the power to do something drastic, and then I pity the loss of innocents, because it will dwarf this auditorium's bloodbath like the sun dwarfs the moon.
