This does not speak to the issue cornelis raises, and that is that "good legislation" is a disruption of free speech by interference or restriction.
In addition to speech that disrupts rightful speech, offensive to the community standard speech is also not rightful as my article argues; that, too, can be banned.
You can't call such bans "disruption of speech" unless you are interested is punsterism. Normally, the word "disruption" is reserved for prevention of activity that is positive in some sense. We don't say "police disrupted a robbery".
