MLK is rightly celebrated as one of the greatest Americans.
Strangely enough, his dream was, in so many ways, the same as that of the American forefathers, but as we all know, President Lincoln accurately noted that America had failed to live up to the ideals of the forefathers. Lincoln noted, quoting the bible, that "a house divided against itself cannot stand." In his own way, MLK saw things the exact same way when he made his great "I Have a Dream" speech.
Each was disturbed by America's failure to live up to the proposition of the forefathers that "all men are created equal" and each prompted men to action. In 1776, the forefathers had a dream, but forescore and seven years later, in 1863, as Lincoln noted, the dream had not been realized. Four score and seven years after that, in 1950, Linda Brown, an young African American school girl, had such a bad experience going to her segregated school that her father took the Board of Education to court, and their victory (propelled by African American lawyer Thurgood Marshall, a future US Supreme court justice) provided some momentum for the civil rights movement, which would take its fullest form just a few years later when an African American lady of great principle, named Rosa Parks, would refuse to give up her seat on a bus.
The common thread in all of the greatest Americans was adherence to principle when such adherence was very difficult. Lincoln didn't budge from his principles, even though states were seceding form the union. MLK didn't budge from his principles when peaceful demonstrations were met with violent responses by the establishment.
Martin Luther King, Abraham Lincoln, Thurgood Marshall, Rosa Parks, and some others. In the area of civil rights, these were Americans who stood tall when standing tall was so difficult. Their memories should inspire us to strive for their ideals, and to fight valiantly for the rights of all citizens.
MLK's dream lives on, and we must dedicate ourselves to its attainment.
