Censorship
When I was an undergrad and working at the public library I had a mother come to the circulation desk and yell at me for letting her homeschooled child check out raunchy paperback novels. I quickly called for the branch manager and she politely pointed out that we did not censure or censor what people checked out of the library and that she as a parent had the ultimate responsibility to make sure that her children were reading what she considered appropriate.
