"but hope is relentless. It doesn’t quit. Neither can we"

"The arc of the moral universe is long... but it bends toward justice."

It's just that the closer you get to the end of that arc, the more you notice that it's not a smooth line. It backtracks and whips back and forth.

We need to grab onto the end of that line, hold onto it, and keep pulling it towards justice.

It doesn't happen on its own.
