Did that magzine in the barbershop include close-ups of spread genitals, hardcore sex, anal and oral sex, group sex, gay sex, bestiality, and so on? And before you tell me I exaggerate, my wife had to deal with bestiality pictures coming off of the printer in the college computer lab where she worked when we were in college (they had the same sort of "enlightened" view of pornography that you do). Yes, that sort of picture is out there on the Internet, and if you are unwilling to say "no" to any of the content that people view on public computers, there is no way to stop people from looking at those sorts of pictures rather than the airbrushed pin-ups you remember as a child, and there are most certainly people who will look at them in public if they are protected while doing so.
So, would you support a modern barber leaving hardcore pornography magazines around where 11 year-old boys can find them? Or should I take that as an admission that you see no problem with exposing children to pornography and think it's harmless?
You said, "my wife had to deal with bestiality pictures coming off of the printer in the college computer lab where she worked when we were in college...."
First, if you wish, please write me your story and I will try to fit it in on my group's web site somewhere. People have to speak out about these things.
Second, if you wish, unless it's too late, you could sue for damages. It has been done before and the library settled for a large amount of money just to keep the case from becoming a precedent that could have protected people like your wife. You see, children are not our only concern. Librarians often suffer from the problems just as you described.
