As our society progresses technologically, Victor Davis Hanson muses at National Review Online that we are regressing in other ways.

We are in such a period of rapid breakthroughs in technology, consumerism, and scientific advancement — equally matched by cultural, social, and political ruin.

Take the question of free speech. Fifty years ago leftist student activists — without iPads and Facebook pages — fought for “free speech areas” in university plazas where they could voice unpopular and even uncouth expression.

Not today.

We may be able to communicate in a nanosecond and send photo images in real time on our cell phones, but someone who was a student at UC Berkeley in the 1960s would today be shocked that there is less free speech on campus than a half-century ago — unless he is a tenured dean who helped to implement the censorship he once opposed.

If a junior faculty member were to write a paper on the racialist undertones of Black Lives Matter, the lack of factual evidence for a campus rape epidemic, or the connection between radical Islam and terrorism, he would likely have to struggle for tenure.

It is not just that a John Ford western could not pass current PC muster, but even modernist raunchy satire such as the 1980s TV hits In Living Color and Married with Children, or the comic career of a Teri Garr or Victoria Jackson, or a movie like True Lies simply could not pass today’s Ministry of Truth.

Free-speech activists, homosexual-rights advocates, feminists, and democracy reformers all privately accept that they are as free to attack the fundamentalism of the Christian Right as they are in real danger — both to their persons and to their careers — should they question Koranic support for widespread current Muslim discrimination against women, gays, and religious reformers. Political correctness has become synonymous with either cowardice or careerism — or both. We damn “Islamophobia” to win social brownie points, but we tune out when there is mention of honor killings or female circumcision. Cheap silence is always preferable to principled but risky dissent.
