Well the admixture happened after the xabash one. This movement of people into Somalia is just a simple fact. Stop obsessing over xabashi Arab fantasies.You’re wrong. Ethnic Somalis don’t have any recent admixture from Arab’s. At all. Habeshis do. Bringing up Bantus in Somalia and Benadiris says nothing about actual ethnic Somalis.
You’re trying to deny well established facts.
