Division?

 

Born Free

Stay free
Where no walls divide you
You're free as a roaring tide
 So there's no need to hide
Born free
And life is worth living
But only worth living
'Cause you're born free

Walls ARE meant to divide you.

The opposite of freedom is to have walls.  The phrase after all is “Divide and Conquer.”  If you accept walls, then you are accepting being conquered.  If life is a Zero-Sum game with walls, then when you win, you take something from others.  If life is a game of growth, not Zero-Sum,  then everyone could have more at the end than at the beginning.

A motto of the United States is “E pluribus unum.  Out of many, one” .  It is the United States, NOT the Divided States. Don’t build or accept walls.
