Obiero,
Your post manifests key signs of a tribalist. Why do you feel the need to argue that you are "not a tribalist" and that you admire guys from wherever? Why could you not ask if there are folks here from Nyanza, without trying to stage a show about your "cool" with guys from Central? why?
Tribalists see Kenya through the prism of two tribes - Kikuyu, and Luo, because these are the bigwigs that matter in Kenya as long as the tribe is the muscle. That is how I can tell you are a tribalist. Ask yourself this: why did it not occur to you to mention the Turkana ... the Dorobo, the Kamba, etc?
