“Oppressive laws do not destroy minorities; they simply make bootleggers.”
Editorial in TheAmerican Mercury (May 1924), p. 26
1920s
Context: The strange American ardor for passing laws, the insane belief in regulation and punishment, plays into the hands of the reformers, most of them quacks themselves. Their efforts, even when honest, seldom accomplish any appreciable good. The Harrison Act, despite its cruel provisions, has not diminished drug addiction in the slightest. The Mormons, after years of persecution, are still Mormons, and one of them is now a power in the Senate. Socialism in the United States was not laid by the Espionage Act; it was laid by the fact that the socialists, during the war, got their fair share of the loot. Nor was the stately progress of osteopathy and chiropractic halted by the early efforts to put them down. Oppressive laws do not destroy minorities; they simply make bootleggers.

The History of Freedom in Antiquity (1877)
Context: It is bad to be oppressed by a minority, but it is worse to be oppressed by a majority. For there is a reserve of latent power in the masses which, if it is called into play, the minority can seldom resist. But from the absolute will of an entire people there is no appeal, no redemption, no refuge but treason.

1800s, First Inaugural Address (1801)
Context: All, too, will bear in mind this sacred principle, that though the will of the majority is in all cases to prevail, that will to be rightful must be reasonable; that the minority possess their equal rights, which equal law must protect, and to violate would be oppression. Let us, then, fellow-citizens, unite with one heart and one mind. Let us restore to social intercourse that harmony and affection without which liberty and even life itself are but dreary things.

Neither Democrats, Nor Dictators: Anarchists (1926)
Context: !-- The majority is, by definition, backward, conservative, enemy of the new, sluggish in thought and deed and at the same time impulsive, immoderate, suggestible, facile in its enthusiasms and irrational fears. --> Every new idea stems from one or a few individuals, is accepted, if viable, by a more or less sizeable minority and wins over the majority, if ever, only after it has been superseded by new ideas and new needs and has already become outdated and rather an obstacle, rather than a spur to progress.
But do we, then, want a minority government?
Certainly not. If it is unjust and harmful for a majority to oppress minorities and obstruct progress, it is even more unjust and harmful for a minority to oppress the whole population or impose its own ideas by force which even if they are good ones would excite repugnance and opposition because of the very fact of being imposed.
And then, one must not forget that there are all kinds of different minorities. There are minorities of egoists and villains as there are of fanatics who believe themselves to be possessed of absolute truth and, in perfectly good faith, seek to impose on others what they hold to be the only way to salvation, even if it is simple silliness. There are minorities of reactionaries who seek to turn back the clock and are divided as to the paths and limits of reaction. And there are revolutionary minorities, also divided on the means and ends of revolution and on the direction that social progress should take.
Which minority should take over?
This is a matter of brute force and capacity for intrigue, and the odds that success would fall to the most sincere and most devoted to the general good are not favourable. To conquer power one needs qualities that are not exactly those that are needed to ensure that justice and well-being will triumph in the world.
