Hi 
 I am glad that you mention range of opinion.  You are writing about a people, it is their copyright, their story which is what you have to access in order to verify. I take the trouble to talk to the the people, record interviews from their stand point.  There are sources which I have not uploaded, otherwise it is your own opinion to claim that the source by that man is unreliable. Who else has said that the source is unreliable? It is taught in Uganda education from primary to University that Luo people are Nilo Shemites. Nilotic just means people who dwell along the River Nile and there are many tribes who dwell along river Nile, some are called Nilo-Hamites.  You could have a political agenda or bias based on your religion. I shall not be engaging anymore with you on this matter.
