RE: Is "Tribalism" Good, Bad or Indifferent? Is "Us vs. Them Our Strength or Our Downfall?

WishingI could see in ultraviolet (alone) doesn't make anything so.
But wishing fuels the imagination.
The imagination fuels invention.
Invention creates change... I come up with a pair of glasses that (safely) allows me to see in ultraviolet.
It's that, or sitting indifferently around on our butts saying "nothing can be helped, pass me another beer."
Both approaches exist.
