Martin Luther King Jr and Robert F. Kennedy use rhetorical devices to convey their speeches for the masses as simple and powerful ideas.

Often, rhetoric's power rests upon the people getting the simple crux of the larger point that the orator is trying to make.
They have to be careful of making a poignant point and not a simplistic or naive one but at the same time they must also take heed.
