There is no obligation on you to make political pictures — if you do not wish to take a strong stand. You are free to confine your work to good, honest, non-political movies. But there is a moral obligation on you to present the political ideas of Americanism strongly and honestly — if you undertake pictures with political themes.
And when you make pictures with political themes and implications — DON’T hire Communists to write, direct or produce them. You cannot expect Communists to remain “neutral” and not to insert their own ideas into their work. Take them at their word, not ours. They have declared openly and repeatedly that their first obligation is to the Communist Party, that their first duty is to spread Party propaganda, and that their work in pictures is only a means to an end, the end being the Dictatorship of the Proletariat. You had better believe them about their own stated intentions. Remember that Hitler, too, had stated openly that his aim was world conquest, but nobody believed him or took it seriously until it was too late.
Now a word of warning about the question of free speech. The principle of free speech requires that we do not use police force to forbid the Communists the expression of their ideas — which means that we do not pass laws forbidding them to speak. But the principle of free speech does not require that we furnish the Communists with the means to preach their ideas, and does not imply that we owe them jobs and support to advocate our own destruction at our own expense. The Constitutional guaranty of free speech reads: “Congress shall pass no laws—” It does not require employers to be suckers.
Let the Communists preach what they wish (so long as it remains mere talking) at the expense of those and in the employ of those who share their ideas. Let them create their own motion picture studios, if they can. But let us put an end to their use of our pictures, our studios and our money for the purpose of preaching our expropriation, enslavement and destruction. Freedom of speech does not imply that it is our duty to provide a knife for the murderer who wants to cut our throat.
