David Brooks' editorial I Am Not Charlie Hebdo in the New York Times is spot on, and I encourage you to read it in its entirety.
A couple of salient quotes from Brooks:
Public reaction to the attack in Paris has revealed that there are a lot of people who are quick to lionize those who offend the views of Islamist terrorists in France but who are a lot less tolerant toward those who offend their own views at home.
Just look at all the people who have overreacted to campus micro-aggressions. The University of Illinois fired a professor who taught the Roman Catholic view on homosexuality. The University of Kansas suspended a professor for writing a harsh tweet against the N.R.A. Vanderbilt University derecognized a Christian group that insisted that it be led by Christians.
The first thing to say, I suppose, is that whatever you might have put on your Facebook page yesterday, it is inaccurate for most of us to claim, Je Suis Charlie Hebdo, or I Am Charlie Hebdo. Most of us don’t actually engage in the sort of deliberately offensive humor that that newspaper specializes in.
In most societies, there’s the adults’ table and there’s the kids’ table. The people who read Le Monde or the establishment organs are at the adults’ table. The jesters, the holy fools and people like Ann Coulter and Bill Maher are at the kids’ table. They’re not granted complete respectability, but they are heard because in their unguided missile manner, they sometimes say necessary things that no one else is saying.
Healthy societies, in other words, don’t suppress speech, but they do grant different standing to different sorts of people. Wise and considerate scholars are heard with high respect. Satirists are heard with bemused semirespect. Racists and anti-Semites are heard through a filter of opprobrium and disrespect. People who want to be heard attentively have to earn it through their conduct.
The massacre at Charlie Hebdo should be an occasion to end speech codes. And it should remind us to be legally tolerant toward offensive voices, even as we are socially discriminating.
