mentioning porn as an example of censorship is disingenuous really, however some literature available could be considered pornographic or at least erotic by some and then banned because some local influential group deems it unsuitable
but then that could extend to religious views etc, slippery slope really
and as for those parents who don't know what is best for their children would not take them to libraries anyway (breath) well other people can very well take them, playgroups, foster parents etc, I would have thought those would be in greater need to have this resource available
and not all Tories are in favour of culling libraries my MIL is horrified at the prospect and for that matter so is FIL with the fiddling going on in the NHS, both lifelong Tories, both NHS workers both sane kind and compassionate people
