A similar question involves minors accessing it at home or in some
public library that bans access to sexually explicit sites.
In my opinion, Public libraries should not permit unsupervised minors to
use the internet unless their parents first, being properly informed as to
the nature of the internet, knowingly and explicitly give the library
permission to do so.
