How about the oromoized Amharas? and the Amharized Tigrayans? how about the Tigrayanized Agews? The Oromized Agews? The Oromized Somalis? The Somalized Oromos? The Tigrayanized oromos? The Oromoized Afars? The Oromoized Argobbas? The Oromized people from Damot? The list is endless actually and it is not that simple, read Ethiopian History. The "real" Oromos now are probably just the Borana.
