Do you believe that artworks should never be censored, or do you think that there are some subjects that should be banned?

Study artworks in this section of the book (4 – Themes) that have been censored or in some other way withheld from public view, or look at other artwork from outside the text which has been censored. Are there any other works you have read about that the public has been prevented from seeing? Do you believe that artworks should never be censored, or do you think that there are some subjects that should be banned? Write an argument defending your belief in the limits or freedom of expression in art, using at least two specific artworks as examples to make your point.

As far as formatting and length and such, I would like at least 400 words, or about a page. Ideally you have have an introduction paragraph which contains a thesis statement, a body of example paragraphs which support your thesis, and a conclusion which summarizes your ideas and opinions.
