s those and countless other examples prove, the concepts of “extremism” and “radicalizing” (like “terrorism” itself) are incredibly vague and elastic, and in the hands of those who wield power, almost always expand far beyond what you think it should mean (plotting to blow up innocent people) to mean: anyone who disseminates ideas that are threatening to the exercise of our power. That’s why powers justified in the name of combating “radicalism” or “extremism” are invariably — not often or usually, but invariably — applied to activists, dissidents, protesters and those who challenge prevailing orthodoxies and power centers.
My arguments for distrusting governments to exercise powers of censorship are set forth here (in the context of a prior attempt by a different French minister to control the content of Twitter). In sum, far more damage has been inflicted historically by efforts to censor and criminalize political ideas than by the kind of “terrorism” these governments are invoking to justify these censorship powers.
And whatever else may be true, few things are more inimical to, or threatening of, Internet freedom than allowing functionaries inside governments to unilaterally block websites from functioning on the ground that the ideas those sites advocate are objectionable or “dangerous.” That’s every bit as true when the censors are in Paris, London, and Ottawa, and Washington as when they are in Tehran, Moscow or Beijing.
