I'll try my best... first of all, Martin Luther King Jr. uses the words "we and our" which show the P.O.V that M.L.K is on their side. "We have waited for more than 340 years for our constitutional and God given rights. The nations of Asia and Africa are moving with jetlike speed toward gaining political independence, but we still creep at horse and buggy pace toward gaining a cup of coffee at a lunch counter." Asia and Africa are used for Logos, since he's logically telling us that our competitors are going to or are zooming pass us. There's also juxtaposition between "horse buggy pace" and "jetlike speed." Another emphasized pathos would be when MLK mentions his young son in tears. 340 years could be ethical as well. Since African Americans got their rights long after the Constitution date, but are still discriminated against. Hope this helped a little!
