In both cases, he was right.
Churchill recognized his people's submission to tyranny in creeping self-censorship. Whether yesteryear's Nazis or today's Muslims, the effect is the same.
Do not be intimidated into silence. Expose evil. Tell the truth.
Those who love darkness rather than light do so because their deeds are evil. If what they do is of God, why do they lie?
From Jihad Watch:
"In a very few years, perhaps in a very few months, we shall be confronted with demands with which we shall no doubt be invited to comply. Those demands may affect the surrender of territory or the surrender of liberty. I foresee and foretell that the policy of submission will carry with it restrictions upon the freedom of speech and debate in Parliament, on public platforms, and discussions in the press, for it will be said--indeed, I hear it said sometimes now - that we cannot allow the Nazi system of dictatorship to be criticized by ordinary, common English politicians. Then, with a press under control, in part direct but more potently indirect, with every organ of public opinion doped and chloroformed into acquiescence, we shall be conducted along further stages of our journey."Here is Churchill on the heresy and bloodlust of Mahomet:
"How dreadful are the curses which Mohammedanism lays on its votaries! Besides the fanatical frenzy, which is as dangerous in a man as hydrophobia in a dog, there is this fearful fatalistic apathy. The effects are apparent in many countries. Improvident habits, slovenly systems of agriculture, sluggish methods of commerce, and insecurity of property exist wherever the followers of the Prophet rule or live.
"A degraded sensualism deprives this life of its grace and refinement; the next of its dignity and sanctity. The fact that in Mohammedan law every woman must belong to some man as his absolute property -- either as a child, a wife, or a concubine -- must delay the final extinction of slavery until the faith of Islam has ceased to be a great power among men.
"Individual Moslems may show splendid qualities. Thousands become the brave and loyal soldiers of the Queen; all know how to die; but the influence of the religion paralyses the social development of those who follow it. No stronger retrograde force exists in the world. Far from being moribund, Mohammedanism is a militant and proselytizing faith. It has already spread throughout Central Africa, raising fearless warriors at every step; and were it not that Christianity is sheltered in the strong arms of science -- the science against which it had vainly struggled -- the civilisation of modern Europe might fall, as fell the civilisation of ancient Rome."
