The European university -- which should be the home of open pluralism, debate, research and thought -- has instead become the paradise of intellectual sectarianism and terror. This new radicalism will reinforce not only political correctness, but also submission to coercion in the West.

"[T]he freedom of Speech may be taken away — and, dumb & silent we may be led, like sheep, to the Slaughter." — US President George Washington, 1783.

Free expression is not needed for "politically correct" or sedative speech, but it is the only protection the minority has from the tyranny of the majority.

An appeal by some French intellectuals, including many Muslim thinkers such as Boualem Sansal and Zineb el Rhazoui, criticized this "intellectual terrorism."

Minority groups claim "safe spaces", but the ones who really need safe spaces are those who disgree with the reigning orthodoxy.

Mohamed Sifaoui was forced to flee North Africa in 1999 after death threats from Islamists, and now lives in France under police protection. His course on radicalization was recently cancelled by Sorbonne University in Paris, which Sifaoui blamed on "the pressures of Islamic associations and left-wing unions."

Western universities have become places of personal fear and intellectual terror. Formerly sanctuaries for open inquiry, instead fierce ideological minorities have been setting red lines of orthodoxy in the face of a silent or, worse, compliant academy. Education -- from ex ducere, to lead out -- has been increasingly eroded by ideological fundamentalism and an attempt to determine not only what actions are acceptable, but even words and thoughts.

Social media has helped by officially reviving the lynch mob. We must now all sing the praises of multiculturalism, Islam, immigration, post-colonial guilt and racializing just about everything. In this new Inquisition, not even the slightest doubt or dissent can be tolerated -- it must be punished!

Freedom of expression is increasingly at risk in France by effectively creating new crimes of opinion. If your personal opinion coincides with the official one, you have nothing to fear. If your ideas conflict with the official ones, you risk becoming ostracized and your mere existence in the public sphere scandalous.

"The new academic fascism," is how Natacha Polony, a television host and editor of the French weekly Marianne, has described it. If you dissent, educators, political leaders, the media and the mob will try to destroy you, just as they destroyed Giordano Bruno in 1600 for saying that the universe could have many stars.

"Small radical groups create a climate of terror to impose opinions and silence their opponents," Polony wrote. "They enjoy infinite mercy from some political and media circles insofar as they claim to embody the Good. Who would dare to challenge them?"

Others -- for views regarded by some as politically incorrect, even if factually correct -- have, in the last few years, been surgically removed from society, or been threatened with removal:

Meanwhile, Islamist regimes are free to continue pouring vast amounts of money into these universities. Research by academics Jonas Bergan Draege and Martin Lestra, published in the Middle East Law and Governance Journal, calculated that between 1997 and 2007, Gulf entities provided at least £70 million to British academic institutions.

An appeal by some French intellectuals, including many Muslim thinkers such as Boualem Sansal and Zineb el Rhazoui, criticized this "intellectual terrorism." It recalls, they wrote, "what Stalinism did to the most enlightened European intellectuals.

"Our cultural, academic and scientific institutions are now targeted by attacks that, under the guise of denouncing 'colonial' discrimination, seek to undermine the principles of freedom of expression and of universality inherited from the Enlightenment".

Defending the freedom to think and the possibility of an open conversation -- both currently mutilated in Europe -- is the foundation of Europe's civic life. Without free expression, there can be no circulation of ideas, no increase in knowledge, and therefore no progress. The basic principles of liberal society are undermined.

"I disapprove of what you say, but I will defend to the death your right to say it," wrote a biographer of Voltaire. Free expression is not needed for "politically correct" or sedative speech, but it is the only protection the minority has from the tyranny of the majority. One does not even need look, for example, toward a country such as Pakistan, where mobs nearly murdered Asia Bibi after she was found innocent.

The United States, upon declaring their freedom from a repressive England in 1776, understood well the primacy of freedom of speech. George Washington told his army officers in 1783: "the freedom of Speech may be taken away — and, dumb & silent we may be led, like sheep, to the Slaughter."

On US campuses it has become commonplace to cancel or protest invited speakers whom a handful of activists consider intolerable. The administrators are evidently too frightened of their own students to ask for the students' suspension, let alone their being expelled or requesting police support. This same type of censorship, regrettably, can now be seen throughout Europe. Minority groups claim "safe spaces", but the ones who really need safe spaces are those who disagree with the reigning orthodoxy.

The European university -- which should be the home of open pluralism, debate, research and thought -- has instead become the paradise of intellectual sectarianism and terror. This new radicalism will reinforce not only political correctness, but also submission to coercion, "like sheep to the slaughter", in the West.
