The internet is a wild free for all. It is an unregulated mass of free speech. It is, for all intents and purposes, the only such unregulated mass of free speech going today. That’s why people love it so. You can put up parody. You can post your made ravings on the convergence of string theory and mozzarella cheese sticks. You can even make stuff up and email it to all your friends. It’s up to the reader to filter out the truth from fiction, just like every other source of information in the world.
The truth is out there. It’s just not the government’s job to make sure that’s what is on the internet.
