Writing for the majority, Justice Anthony Kennedy emphasizes the internet's vital importance to freedom of speech. "This case is one of the first this Court has taken to address the relationship between the First Amendment and the modern Internet," he says. "As a result, the Court must exercise extreme caution before suggesting that the First Amendment provides scant protection for access to vast networks in that medium."

Kennedy says North Carolina's law "enacts a prohibition unprecedented in the scope of First Amendment speech it burdens," applying indiscriminately to many kinds of online activity, even when it has nothing to do with contacting minors. "By prohibiting sex offenders from using those websites, North Carolina with one broad stroke bars access to what for many are the principal sources for knowing current events, checking ads for employment, speaking and listening in the modern public square, and otherwise exploring the vast realms of human thought and knowledge," he writes. "These websites can provide perhaps the most powerful mechanisms available to a private citizen to make his or her voice heard....To foreclose access to social media altogether is to prevent the user from engaging in the legitimate exercise of First Amendment rights."

In my state, teenager/teenager consensual sex has been equated with forcible rape and aggravated child molestation. This blurs the registry system by labeling essentially normal persons as perverts and prohibiting them from jobs, housing, and a normal life.
