This country has to protect itself against a new and insidious menace. … Not all of our enemies work in the light of day. Those … most dangerous to our public security and peace today are doing evil work in the dark. … They … evade our laws, while … working secretly to destroy those laws by force. … At the same time they appeal to these same laws for their personal protection. … In this free land of ours in recent years we have been permitting the growth of the most sinister organisation for evil the world has yet seen. An organisation with … one object and one only: the forcible destruction, at first by secret methods and then by open methods, of our liberty, our constitution, our laws, our religion, and our heritage. … These men intend that we shall be subjected to the tyranny of a powerful alien body which has never enjoyed our freedom or any freedom; which hates all who have enjoyed this freedom, and is determined that we shall enjoy it no longer. … The time has come when we must say … : ‘Come to our free country and learn to be free, but you must behave yourselves properly while … here.’ … These men … are out for their own power: absolute power to control the liberty of every [Briton]. … These attempts to subvert and dominate our democratic system are being made by … extremists. … We must … excise this social cancer before it does fatal mischief.1 [my italics]
