This assumes there are no negative externalities to the curtailing of free speech, which is laughably untrue. People now are no less rational than they have been the past few centuries when free speech was allowed to prosper unmolested. And they are no less grasping and unscrupulous when it comes to the reasons unbridled free speech was held up as an exemplar to begin with. The fact that the result of all this censorship and narrative massaging has indisputably been the pushing of harmful agendas is illustrative of the above.
