The South Dakota State Capitol Building
An historic mural by an artist with works on display "in libraries in Detroit, Kansas City, the New York City College (now C.C.N.Y.), M.I.T., Grove Academy of Athens (Georgia), Baltimore and Cleveland court houses... the obverse of the 1896 Two Dollar Bill... the dome in the Jefferson building of the Library of Congress..." was covered up by order of Governor Bill Janklow in 1997.
Spirit of the West is the artist's tribute to "Manifest Destiny," the American civil religious idea by which Western civilization spread across the continent and also destroyed the existing Native culture.
Sensitivity to Native American pain resulted in the painting's removal from public view, despite earlier efforts to recast it as a reminder and warning of historic misdeeds.
Go to the link and read the whole account. Sometimes, people of good will decline to assert a right (in the mural's case, free speech) in order to show respect for a neighbor.
This is all that is being asked of the Cordoba Mosque developers in NYC. Just build it at another location.
