2 reasons:
1) I asked you a question first to which you have not responded. Until you respond, you owe me an answer, and I owe you nothing but withering contempt and increasing laughter at your expense.
2) Your questions are simply far too stupid to warrant a serious response. You are a self-parody. They are of the caliber "Well, you've got dark hair, and Mao had dark hair, so why do you like looking like a mass-murdering Communist? Huh? HUH?". And don't let me dissuade you from the same line of questioning. Everyone here finds it priceless in its amusement value.
You've just about got my attention now. One last chance for you to engage your survival instinct, and answer my question:
Have you read and/or researched any of the data from the responses posted to you on this thread?
Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.
