Unpopularity

"Moral courage is the rarest of all the rare things of this earth.

The war has shown that millions have physical courage.
Millions were willing to face rifle and cannon, bombardment, poison gas, liquid fire, and the bayonet; to trust themselves to flying machines thousands of feet in air, under the fire of anti-aircraft guns of enemy planes; to go into submarines, perhaps to meet a horrible death.
But how many had the courage merely to make themselves unpopular?

The bitter truth must be told:
the many enlisted or submitted to the draft on both sides of the conflict not because they were convinced that they were helping to save the world, not because they had any real hatred for the enemy, not to uphold the right, but simply that they hadn't the moral courage to face the stigma of "slacker" or "conscientious objector." ...
Fear of death?
No; the soldiers faced death bravely. But they feared unpopularity.
They dreaded the suspicion of their fellows.

What was needed in war is needed no less urgently in peace.

How many persons in public or even in private life have the courage to say the thing that people do not like to hear?"

– Henry Hazlitt (via CN)
