I'll have to click the link at home... work block. There was a magazine 6 months (?) ago that had controversial quilts. I believe one showed someone giving birth, one showed something with Jesus, things like that. And the publisher put the magazine in a plastic bag to avoid complaints about the "explicit" nature.
I agree that anyone should be able to express themselves however they want. I also think that there should have been a warning or separate area, because the viewers have the right to not see it for whatever reason. So not censorship, but a way to respect the opinions of all involved.
