It certainly covered a lot of ground, you have to give him that -- as a preacher and icon, Dr King has played utterly key roles in the campaigns:
-to end segregation and for equal voting rights
-to end the War in Vietnam and for a Greater Peace
-for economic justice and ending poverty in America
-against the incarceration frenzy of the 1970's and for a rehabilitative justice system
-against the "decay of the family" especially in the black community*
-against the rise of drugs* and the "violent culture"
-to "protect the unborn everywhere in America"
-to defend the unionized industries in America and spread collective bargaining to her growing industries
-to defend teacher's pay and fight cuts in public education
