The Letter's Point

Well of course the overall point to this is that racial segregation is wrong, but more specifically, MLK Jr. wants to make it clear here that a change cannot be made by negotiations through the court system. In order for a direct change to take place in the realm of civil rights, Dr. King suggests "nonviolent direct action." This was a great idea and and the letter surely helped racial segregation and racism slow down to the point where it is now which was the point of the letter in the first place.
