does not imply the greatest exploitation. It is apparent that
important minority rights are recognized in various aspects of
our national life. We do not have juke-boxes in the Library of
Congress, peanuts are not sold in the aisles of our cathedrals,
cigarette advertisements are not displayed in the National Gallery
of Art. The sanctity of a church, a gallery of art, or a great
temple of nature depends upon a concept of appropriate use.
