The U.S. Postal Service designated him an unpaid special agent, giving him the right to go into any post office in the nation and open mail he believed to be obscene. The new Anthony Comstock is Senator James Exon, and instead of a sack, he prowls the halls of Congress with his Blue Book, a collection of obscene and indecent materials he has downloaded from the Internet. He and others like him appear to think that the Internet is a million-armed hydra, reaching into every American household to strangle the children. There is pornography on the Internet. There is explicit but legal sexual material , which Senator Exon would outlaw with the vague provisions of his Communications Decency Act.
Free speech is sloppy.
The reason the First Amendment protects almost all speech is that, with very limited exceptions, we have never succeeded in agreeing which speech is good and which is bad. Pornography which falls short of the legal definition of obscenity may be freely distributed. Well, says Senator Exon, they are pervasive. They come into the house. Ten year old children who understand the computer better than their parents do, will find them.
