This is not news and that’s 1% of the problem. Historically in the last 900 years, the Muslim Amharans, Tigrayans (also known as Jeberti to avoid confusion) and the Saho Muslims have been at war with the Abysinnians (Orthodox Amharans and the Tigrinya-Tigrayans) then followed by Afar, Beja, Harar, Oromo, Sidama and so on then spread throughout the Horn from the year 1200 to 1990s.
They’re segregated from Muslims, don’t eat and refuse to eat from Muslims and follow the doctrine of anti-Islam Abyssinian extremist Yekune Amlak to Ras Alula who believes that all Muslims should be baptised or be deported to Mecca and are responsible for inciting centuries of sectarian and religious wars, killing hundreds of thousand Muslims and forcibly assimilating and baptizing ethnic groups since the fall of the Agew dynasty.
They’ve reached to the point where they effectively removed the Muslim
identity in Eritrea and Ethiopia in the 20th century that reached to the highest peak of atrocities commited by them (due to the advancement of modern weapons), destroying 10,000s of mosques, ethnicically displacing millions, barred them from having any voice and portrayed it as Christian nations.
Anyone with deep knowledge in those two nations from ethnicities, regions and history from their perspective will know it’s rubbish. If they leave qabil aside, the Amharan and Tigrinya-Tigrayan domination will fall like in the olden times.
