The best way to rebut speech you disagree is with speech of your own. In Washington, a more common tactic is simple intimidation. Cato president John Allison’s response when faced with just that is a thing of beauty. Quoted in full, here is his letter to a man seemingly incapable of disagreeing agreeably:
Dear Senator Durbin:
Your letter of August 6, 2013 is an obvious effort to intimidate those organizations and individuals who may have been involved in any way with the American Legislative Exchange Council (ALEC).
While Cato is not intimidated because we are a think tank—whose express mission is to speak publicly to influence the climate of ideas—from my experience as a private-sector CEO, I know that business leaders will now hesitate to exercise their constitutional rights for fear of regulatory retribution.
Your letter thus represents a blatant violation of our First Amendment rights to freedom of speech and to petition the government for a redress of grievances. It is a continuation of the trend of the current administration and congressional leaders, such as yourself, to menace those who do not share your political beliefs—as evidenced by the multiple IRS abuses that have recently been exposed.
Your actions are a subtle but powerful form of government coercion.
We would be glad to provide a Cato scholar to testify at your hearing to discuss the unconstitutional abuse of power that your letter symbolizes.
Cato scholar Ilya Shapiro, who has tussled with Sen. Durbin on free speech issues before, has more.
