This piece by exiled Frenchman Olivier Tonneau is perhaps the best I've read in the wake of the Charlie Hebdo attack. Tonneau argues eloquently that the terrorists were utterly illogical in targeting a publication that savaged all religions equally and, moreover, championed minority rights and fought against racism.

Liberty is but hypocrisy when elements of the French population are being routinely discriminated against. But fraternity is lost when religion trumps politics as the structuring principle of a society. Charlie Hebdo promoted equality, liberty and fraternity – it was part of the solution, not the problem."
