You're entitled to that view, but that's just plain silly. Any logical person sees the value in having standards as a community. Communities have standards. Libraries are funded by the community so that community should have a say in what is available at the library. Don't like it? No problem, you are free to buy whatever you want, the community doesn't have to buy it for you and make it available at the library.
It's not at all silly. If a majority of people in a community want to do A, B, and C.. and don't want there to be X, Y, and Z.. then they can do a perfect job of that on their own... they don't need their government to tell them to do it. It is, ultimately, the people that make a community what it is, not a government mandate.
These are complaints about what the libraries have bought, not about what hasn't been bought. It's also not about money, either. Even if you go to the top 50 books people file these complaints about (if there is 50 books that people complain about), that's still a drop in the bucket in terms of cost.
There are hundreds of other books for them and their children to read.
No, these are people complaining because their morals/beliefs are offended... when the real problem is that they think it is the government's (or the library's) job to protect/prevent them from being offended.
Now if we start talking about censorship, that's a different ballgame. I don't believe in censorship at all, let adults make their own decisions. Setting standards for what is age appropriate makes perfect sense and does not censor anything.
Setting standards is what parents should be doing for their own children... not government.
