There is very little that is special about the Japanese and have zero contribution to world history, you can't even compare them to the Chinese. The worlds great contemporary civilizations are Islamic, Indian, Chinese, and Western.
The West has every right to do so because they see themselves consciously and are the inheritors of Greco-Roman civilization. Hell the Romana saw themselves that way about the Greeks. It's all fair play.
Sxb you distance yourself from Arab, for why? Because you don't see yourself as Egyptian or Saudi or Iraqi? Well you are not, but you still share that civilization. But don't forget we have culture, but so do Saudis or Moroccans, but it is inline with Islam vis a vie Arab civilization. Remember a civilization can have many local cultures.
have you ever asked your father or mother what life was like when they were kids? if not, ask them? ask them whether women wore hijabs and jilbabs? ask them how common it was for them to pray? you might be surprised what you learn. contrary to your assumptions, this idea that somalis shared a "islamic civilization" with the arabs is simply not accurate. somalis were muslim largely in name for most of our history.
Read Sir Richard Burton's book "First Footsteps in East Africa". He was the first white man to travel to Somalia in the mid 1800s. His descriptions of the life of Somali nomads is among the most ancient you will find. In the book, he mentions that the Somali nomads of that time had very little knowledge of islam. He was actually welcomed by the Isa tribe (who he traveled with) because they thought he was an carab and that he would teach them about the quran and islam. It seems as though for much of our history, we really were only muslim by name.
Look back at some of the old pictures taken by the italians or british when they first came upon somalis. you'll see that women didn't cover their hair. some even used to have their chests exposed like some of the isolated Afar tribes in Ethiopia. Somali women definitely did not wear jilbabs or whatever other carab clothing that is now popular. Somalis also didn't pray that much. My father said when he was growing up (1960-70s), praying was not really part of culture. there were the few who were very religous but it wasn't as uniform in somali culture as it is now.
so other than self-identifying as muslims, somalis really had no tangible connections to "Islamic Civilization" or "Arab Civilization." Somalis (before the 1990s) were far closer in culture to their nomadic East African neighbors (Oromo, Afar, Masai) who were not muslim than they were to their muslim neighbours in Arabia or North Africa.
We both know only a few clans claimed arab descent and even they were 100% Culturally and liguistically Somali. And now, thanks to genetic study, we have found they are 100% genetically Somali as well.
Waxaad ku haleysid bal eeg, miyaanad isla yaabeYn? 40% of SL can bearly read somali let alone speak another language fluently. Why don't you become a government spin-doctor? You have a talent for bullshitting.
