In light of recent events, and in light of this thread, I believe the next logical step is to change the MU logo and disable, or at least restrict, the noose imagery in games.
In US culture, the noose symbol is effectively the icon of lynching, much like the cross is the icon of Chritianity. The ADL notes:
The hangman's noose has come to be one of the most powerful visual symbols directed against African-Americans, comparable in the emotions that it evokes to that of the swastika for Jews. Its origins are connected to the history of lynching in America, particularly in the South after the Civil War, when violence or threat of violence replaced slavery as one of the main forms of social control that whites used on African-Americans. The noose quickly became associated with the Ku Klux Klan.
