The Librarydude!

At the moment we have a display about a pretty hot political topic in our library, (treatment of refugees and asylum seekers). I'm surprised this has been allowed to return, as we had some rather violent reactions to this display last year. (Pieces of it were thrown at staff). Even with a fairly prominent disclaimer stating that These are NOT the views of the Library Service, we still get people making comments to us, (and usually negative ones). I'm not sure if this would be censorship, (something I'm completely against) but wouldn't it be better to not have displays that are political hot potatos. It seems the Library staff are the main target for peoples anger about this topic. We are not paid to be verbal punching bags. How do other libraries cope with this type of problem?
