Grassroots groups should be indignant that their tax dollars are subsidizing, not only pornography, but a left-wing agenda bent on turning our moral standards upside down. Well, first, find out if your local library has open access to the Internet, but you should know that the ALA trains its members to evade these kinds of questions. You may be told, for example, that the Constitution doesn't allow computer software that filters pornography. That's not true. No law has ever required a library to include smut in its collection.
Librarians make judgments every day.
Some libraries, as you well know, ban Christian books. And indeed, librarians have the right to screen out vulgar websites, just like they screen anything else. You might be told that filtering software is unreliable, that it can't distinguish between legitimate health information, like breast cancer, and pornography. But a study of Utah public schools that use filtering devices found only one site in a million was ever blocked in this way. Some libraries that do reject the ALA's dictates are already banning obscenity from their computers, while maintaining legitimate links to the Internet.
