What were MLK's contributions, other than generating support for more federal government power and interference, and making "discrimination" a "bad" word? "Discrimination" means "choice". We discriminate every day - if we didn't we'd die. Discrimination is a good thing. We need to recover our lexicon that freedom of discrimination and choice is the God-given right of every individual as long as it does not interfere with anothers life & freedom.
Credit MLK for stirring up consciousness about the mistreatment of blacks and others. God bless him. Credit him for stirring up other blacks to snap out of a stupor and "get in the game" with courage and determination, the way Bill Cosby talks to the black community. God bless him fight for what you want.
But MLKs agenda was to sir up GOVERNMENT to FORCE what MLK wanted on non-blacks. The valid Constitutional issue was against STATE LAWS (not individuals) requiring SEGREGATION (not integration). But MLK contributed to influencing government force on the individual and to force integration. That was a contribution of a giant shove towards Socialism and tyranny.
