Whether you're concerned with the bad science and politics behind "global warming", the genuinely lunatic and self-destructive politics of the Western Left, or the current state of denial almost everyone is in regarding Islam, you can't say much more than George Orwell already has:

During times of universal deceit, telling the truth becomes a revolutionary act.

Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

In our age there is no such thing as 'keeping out of politics.' All issues are political issues, and politics itself is a mass of lies, evasions, folly, hatred and schizophrenia.

One does not establish a dictatorship in order to safeguard a revolution; one makes a revolution in order to establish a dictatorship.

Political chaos is connected with the decay of language... one can probably bring about some improvement by starting at the verbal end.

Political language... is designed to make lies sound truthful and murder respectable, and to give an appearance of solidity to pure wind.

The very concept of objective truth is fading out of the world. Lies will pass into history.

There are some ideas so wrong that only a very intelligent person could believe in them.

We have now sunk to a depth at which restatement of the obvious is the first duty of intelligent men.

What can you do against the lunatic who is more intelligent than yourself, who gives your arguments a fair hearing and then simply persists in his lunacy?

Who controls the past controls the future. Who controls the present controls the past.

Whoever is winning at the moment will always seem to be invincible.
