ome of these laws aren't "difficult" to enforce, they're impossible to enforce. And it's not because the internet is some "wild west," but because it's a very different platform of communication -- a many to many platform, which the world has not had before. We've had one-to-one and one-to-many forms of communication, but a many-to-many platform really does change some important fundamentals when it comes to speech.
Far more important are the questions of internet access to unsuitable material, especially but not solely by children, as well as the danger to children from inadequately policed social media. Merely to write such a sentence is to invite outrage in some quarters, but these issues are all too easy for a society to ignore until they return to haunt us.
And the proper response, if there is "unsuitable" (unsuitable to whom, by the way?) content is to go after those who produced and distributed it. Not to seek to block access and sweep it under the rug. That's denial. Let's live in reality.
