On my more cynical days, this what I see:

If you were to think of human experience and diversity as a scale from 1 to 100, most people are only comfortable with the range from 49 to 51. And they all think they are God's Perfect 50.

Everything that falls outside of that narrow, familiar band might as well be from some hostile planet in another galaxy. If you're a 52 you might as well be a 99. And all of mankind's Labels of Fear and Loathing await you -- sinner, freak, weirdo, deviate, sick, disabled, evil, etc. etc. etc.

Personally, anybody between 40 and 60 bores me to tears.
