WHY would we kill each other?
1) They want to kill us because they are, for lack of a better term, possessed by trans-corporate intelligences (demons) who are committed to the torture and extermination of mankind.
2) We want to kill them (or should) because if we don't, the entire race of man will be a screaming horror right up until the point we become extinct at the hands of "Allah".
Understand why now?
Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.
