Its a male, he goes under the name Magherbin on Wikipedia, a deluded Harari nationalist who envies the role Somali people, and Somali men in particular have played in the history of the Horn, East Africa and other parts of the world, hence why he tries to diminish it at every turn, not realising he is doing the opposite. He is in his 40s and as you can see from his months of larping he is clearly not well spending most of his time pushing propaganda on Wikipedia.
Its interesting though that a Harari of all people would bear such ill-will towards the Somali people, when we are the only major group in Africa that want the Harari to succeed and thrive, while the others are slowly absorbing them to extinction.
His misplaced anger makes sense though, if you look at all the important urban centers of the Horn with the most history and acclaim, most of them are all in Somaliweyn or heavily influenced by us. The group mentioned the most in historical manuscripts are us and our subgroups, all major historical figures are linked to us, while major unidentified groups like the Harla are all closely tied to Somali clans, including their language and most likely represented a Somali farmer group the way the Tumal were blacksmiths and the Somal were pastoralists. With the collapse of the major sultanates the latter and its lifestyle prevailed and became the name under which we all identify today.
The worst thing that can happen for these guys is for Somalia to settle down and a ton of archaeologists to start putting down roots in our region and retrace each century, because their time and effort will only serve us since we have been here before any other modern group.
