> Going a step further, there's nothing inherently wrong with censorship.

So long as they're censoring the things you want them to censor. Of course, everybody would like something different to be censored, which is why it's better to err on the side of "no censorship". There's a reason librarians tend to fight against any form of censorship.

I think even the more politically minded librarians are OK with a private company deleting a blog that has child pornography images on it.

Unlikely, since if it was art (and not photographic porn), most of the librarians work in libraries with manga collections.
