Cultural relativists like to talk about dialogue. They tell us that we need to engage in dialogue with people who are different from ourselves so that we can understand their perspective and become more tolerant. They tell us that we must listen to the voices of the marginalized and the excluded so that we can rethink our assumptions about the world.

But now that cultural relativists are well-situated in the White House and Congress, dialogue is under assault.

In its proper place, dialogue is essential to the human experience, and especially to a free society. It is the primary way that we interact as rational beings, something that no other species can do. Our very form of government is built on dialogue. Our Founders envisioned a republic where the best people in the country would gather in the halls of Congress to debate vigorously on behalf of their constituents. From city councils to the U.S. Senate, our republic is designed to facilitate discussion.

Anytime somebody-Left or Right-tells us that an issue is too important or too unimportant for debate, we should be suspicious. We should be suspicious when academic elites who help to shape our political ideas shut down scientific discussion about issues like evolution and intelligent design. We should be suspicious when Al Gore tells us that the debate about global warming is closed. We should be suspicious when President Obama declared on the eve of the stimulus package vote, "The time for talk is over."

Then we were told during the stimulus vote that there was no time to read the bill. It was an emergency, after all. Our leaders proclaimed that the economic mess (caused by President Bush, they reminded us) was so dire and the need for intervention so desperate that there was no time for talk. Among other consequences of stifling debate, Bill Clinton's greatest policy achievement, the Welfare Reform of 1996, was largely overturned. Most Americans still don't know about this radical abandonment of a successful policy.

Now, bureaucracies are quietly ushering through other major regulatory changes. The U.S. Customs and Border Patrol, for example, has proposed an expanded definition of switchblade knives to effectively ban the importation of a wide variety of knives. Though this change has important Second Amendment implications, U.S. Customs and Border Patrol has insisted all public comments be submitted by mail and the comment period be limited to an inordinately brief 30 days, hardly sufficient time for a thorough airing of opinions.
