Unanswered question!

This question has been asked over and and over again a lot of times, but has always remained unanswered. 

Why Somalis are considered Arabs since they are genetically Africans?
Why some of our people are more Arabs then the Arabs? 

Some say because Somalia is part of the Arab League? So, Could that make us an Arab? 
I personally believe NO. But I heard that it was Somali government in the 70s that thought it would be good for trade and they lobbied their long history and connection with the Arab world to get in. The government even made Arabic the official language of the state, i think It was for political and economical support. Where the government of Somalia portrayed Somalia as an Arab speaking state (90% of Somali's can't speak Arabic), when Somalia was lobbying to enter the Arab league.

For Somalia, the Arab league served as a geo-political purpose. The league was based on an interrelation of politics and geography for Somalia. It was based on the combination of politics/economy/religion for Somalia. 

I would love to hear/read your view on this.
