Every tyrant wants to silence the voices that do not support him.
A baby cries at birth - because someone pats him on the popo to start him inhaling oxygen.
We cry out from the start so we can breathe. That is the way to survive and to thrive. No one has a right to smother the cry of a human voice.
The only limit to that freedom is the freedom of another to speak and to live without fear or injury.
