No, she's certainly Somali. No common foreigner can know so much about our language and culture. But she is certainly Ethiopian as well. Actually... I very much doubt she is even Ethiopian, probably full Somali.
Check her old comments she defends Ethiopia with tooth and claws. Plus, most half Somalis are patriot and love Somalia.

Color me surprised that your curriculum in Deutschlandia may have been different.
I thought it was a Dutch/Belgian thing. Also they definitely cover it properly in the UK. The average student in the UK has far more time to cover things like that since your timetable isn't anywhere near as packed. A lot of subjects such as Greek, Latin or classical studies that are considered mandatory in Gymnasium aren't even available as optional subjects. Strangely enough, a lot of topics like the Hutu-Tutsi conflict are covered in citizenship instead of history.
