Exactly, we need to stop saying nigger.
Even if it's really appropriate to say nigger, just don't say nigger.
Tell other people to stop saying nigger. Approach random people on the street and tell them to stop saying nigger. Pay to place ads on the subway that say "STOP SAYING NIGGER" in big letters. Fly a plane with a banner that says "STOP SAYING NIGGER" over a major American city. Pay a skywriter to write out "STOP SAYING NIGGER" in the clouds. Send a satellite to space that broadcasts "STOP SAYING NIGGER" in Morse code to the entire solar system.
