That is not the issue. Not even remotely.
If it were just about "loss of information," the ALA activists would be willing to take a reasonable position on what can or cannot be viewed on these publicly owned internet access points.
"Reasonable" is defined in the same sense that libraries do not prominently display Playboy, Penthouse, Hustler, etc. on the normal magazine racks -- if they have them in-house at all. It's quite simply inappropriate for a publicly-owned enterprise to distribute smut.
Instead, the ALA has taken a preposterous all-or-nothing approach that can best be interpreted as yet another extension of the libertine sexual agenda that we see wherever liberals make their homes.
