Calvin and Hobbs, the comic strip, has been banned in Tennessee schools on the grounds that it had pornography in the form of Calvin's naked butt being in some cells.
What is adult content? A cartoon butt? A book on breastfeeding? "I can't define porn, but I know it when I see it" has led to Calvin and Hobbs being banned.
I think the point they were making is that a child can walk into a library, pick up any book, and open it. All without any adults being in the loop. They can do that today.
Yeah, and my point is that the "pick up any book" thing is hiding the
fact that selection is in fact seriously limited.
And second, underaged kids can not checkout non kid material without
adult in the loop. That part is simply not true, the librarian will
say no to the child or ask for parents permission.
I have been to my library yes. You don't need ID or a library card (unless you want to check something out or use a computer) and you can pick up any book you like (including e.g. 50 Shades of Grey), sit down at a table, and read it. There are children in there all the time and there isn't an adults-only section.
Pretty much none which is exactly why the comparison to libraries makes zero sense.
And yes, there was considerable pearl clutching over same sex kiss. To the point the supposed old school bastions of freedom would not print it, would not put it in the library and would do everything possible for kid not to read it.
The physical world of back then was considerably more restrictive in terms of what kids could access. Whether in the libraries or outside of them.
