1. The Gallas who chose to drop the word were weak-minded to give in to ethnic stereotypes. Just because of some group attached a stereotype, sociologists can tell that it is most common around the world, you do not change your ethnic name. You change your ethnic name for other reasons, especially, during religious and linguistic transitions into new identity.
2. The history of these numerous herds of people before they adopted the name Orom, before 1991, otherwise considered 'savages' by historians and travelers, will be lost in due time arguing that all histories that bore the word Galla had stereotype in them, which is far from the truth.
I do not support Galla independence from Ethiopia because Galla is an oppressor, not oppressed group. Gallas have not been discriminated by economic or political opportunities. There are poor and filthy(gimatam) rich Gallas. There are ordinary individuals with no power and there are powerful individuals in the Ethiopian government. There are criminal Gallas and there are judges of justice Gallas. One just cannot break up a country for the sadistic pleasure of it.
Secondly, Gallas are new migrants from Kenya, pushed out by the Kikuyu's northward migration and the Lou's eastward migration. If they have no claim to the land they live on in Ethiopia. When they migrated to Ethiopia, they displaced natives by massacres. In some cases, for fear of their savagery, many tribes adopted their Galla language. For example, Chebo Gurages of Tulu Bolo and Weliso who such great personalities such as Tilahun Gessese, President Girma W.Giorgis and Finance Minister Girma Biru. Arsi Oromo were formerly Hadiya speaking groups Gallas savagery is the reason for their adoption of Oromo language. Guji is the same. Whole of Hararge is another victim of Galla savagery. Gojjam and Wello. From south of Gojjam to Lake Chala used to be the land of the semetic speaking group of the Gaffats. From Afar passing thru Entoto, Addis Abeba and Ankober to Harar city used to be the land of the Argobas. So on and so forth.
Glallas claim for independence from Ethiopia taking the land they stole from the native Ethiopians is like your guest claiming ownership of your house just because he spent 24 hours in it.
