Liberals believe in the utilization of government's enforcement mechanisms, whether they be taxation or the barrel of a gun, to force societal change, in an attempt to achieve what they believe would be utopia. Those who would censor or ban certain forms of free speech "for the benefit of society" seem to me to be far more liberal than those who'd let the free market dictate the same.
True freedom is not advanced in the permissive society, which confuses freedom with license to do anything whatever and which in the name of freedom proclaims a kind of general amorality. It is a caricature of freedom to claim that people are free to organize their lives with no reference to moral values, and to say that society does not have to ensure the protection and advancement of ethical values. Such an attitude is destructive of freedom and peace.
