Was thinking about that old saying the other day and it just started to bug me...
  1. In most monarchies, royalty is a birth right, not something bestowed upon one for physical attributes.
  2. If this kingdom was built by the blind for the blind, I would think having sight would not be that big of an advantage. I'm thinking it would be a VERY blind-friendly place.
  3. The sighted man could very well be looked upon as an outcast, a pariah, a freak.
  4. This one-eyed man could be a total idiot, a racist, a misogynist, a serial killer... Let's NOT hand the kingdom over to him just because he can see a little!
