Indiscriminate tolerance and indiscriminate condemnation are not two opposites: they are two variants of the same evasion.
Ayn RandDictatorship nations are outlaws. Any free nation had the right to invade Nazi Germany and, today, has the right to invade Soviet Russia, Cuba, or any other slave pen. Whether a free nation chooses to do so or not is a matter of its own self-interest, not of respect for the nonexistent 'rights' of gang rulers. It is not a free nation's duty to liberate other nations at the price of self-sacrifice, but a free nation has the right to do it, when and if it so chooses.
Ayn RandThere is a fundamental moral difference between a man who sees his self-interest in production and a man who sees it in robbery. The evil of a robber does not lie in the fact that he pursues his own interests, but in what he regards as to his own interest; not in the fact that he pursues his values, but in what he chose to value; not in the fact that he wants to live, but in the fact that he wants to live on a subhuman level.
Ayn RandThe greatest threat to mankind and civilization is the spread of the totalitarian philosophy. Its best ally is not the devotion of its followers but the confusion of its enemies. To fight it, we must understand it.
