WASHINGTON -- In 1977, when a bunch of neo-Nazis decided to march through Skokie, a suburb of Chicago heavily populated with Holocaust survivors, there was controversy as to whether they should be allowed. I thought they should. Why? Because neo-Nazis are utterly powerless.
Had they not been -- had they been a party on the rise, as in late-1920s Germany -- I would have been for not only banning the march, but for practically every measure of harassment and persecution from deportation to imprisonment. A tolerant society has an obligation to be tolerant. Except to those so intolerant that they themselves would abolish tolerance.
Call it situational libertarianism: Liberties should be as unlimited as possible -- unless and until there arises a real threat to the open society. Neo-Nazis are pathetic losers. Why curtail civil liberties to stop them? But when a real threat -- such as jihadism -- arises, a liberal democratic society must deploy every resource, including the repressive powers of the state, to deter and defeat those who would abolish liberal democracy.
Civil libertarians go crazy when you make this argument. Beware the slippery slope, they warn. You start with a snoop in a library, and you end up with Big Brother in your living room.
The problem with this argument is that it is refuted by American history. There is no slippery slope, only a shifting line between liberty and security that responds to existential threats.
During the Civil War, Lincoln went so far as to suspend habeas corpus. When the war ended, America returned to its previous openness. During World War II, Roosevelt interned an entire ethnic group. His policies were soon rescinded (later apologized for) and shortly afterward America embarked on a period of unprecedented expansion of civil rights. Similarly, the Vietnam-era abuses of presidential power were later exposed and undone by Congress.
Our history is clear. We have not slid inexorably toward police power. We have fluctuated between more and less openness depending on need and threat. And after the 9/11 mass murders, America awoke to the need for a limited and temporary shrinkage of civil liberties to prevent more such atrocities.
Britain is just now waking up, post-7/7. Well, at least its prime minister is. His dramatic announcement that Britain will curtail its pathological openness to those who would destroy it -- by outlawing the fostering of hatred and incitement of violence and expelling those engaged in such offenses -- was not universally welcomed.
