Unless those who have agenda of course in dividng Ethiopian people, obviously that is the goal.
There were individuals also even before Tplf took over, when Ethiopians were cohesive society, these individuals (not Ase Menilik, or H/Selassie who were the best democratic leaders ) of all time, deliberately and obsessively out there to look down on others target ethnic groups with insults. These individuals go all over Ethiopia and spit their poison of ethnic insults which today, Tplf used it perfectly to divide Ethiopians and target the entire Amaras especially good Amara people who lived in peace and who did great for Ethiopian people with others are in general being attacked today.
Those who attack ethnic groups who call themselves Ethiopians, ( not talking about Tplf/Olf who have their own and obvious agenda) these individuals then are those who are now coming out today, are the most weak in fact more dangerous because they are dividing Ethiopian people further the danger is you can't separate them away from Ethiopia, as supposed to Tplf/Olf. That is what makes it dangerous. This means indirectly they are supporting tplf/olf further dividng the Ethiopian society and in the first place, they have no idea what Ethiopia is and when Ethiopia is facing the most challenging times, and you spread further the division is weakness. If you can't help attacking the entire society because of individuals, and you have a problem filtering and can't differentiate between the wheat and chaff, that means you have within internal prejudice that is innate. These people then would further affect Ethiopia seriously. The problem is there are not true leaders (not talking about Ethiopian leader) but organizing and forming good leaders who can unify Ethiopian society within and outside of the country.
Re: Why are those people focus on ethnic insult?
In my opinion,most folks out here are special sub-set whose one and only one brand unashamedly is preaching a particular linguistic group (in millions) is an enemy of another linguistic group of millions. Although this is an utter stupid mind set, these special deviant subset are doing it for pecuniary or monetary gains. Let's say this marketing branding of using one against the other gets outdated, they will certainly devour their own supposedly enclaves tearing it apart into hundreds of pieces, a case in point is TPLF. As we we know the tribal lord TPLF is not , for instance, standing for the Tigre people as it is preaching. TPLF is an exclusively Adawan based, on the ground there are different segments of the province population who are subjected to brute ethnocracy( I mean Adawacry). The same is true about OLF, the Bale or Arusi thugs, occupied and exploit the Shewan people in the name of Oromo, etc. From history, we know there are two parties, namely the people (subjects) and the ruler. The rulers (kings) exploit their subjects not one people rules another people - we did not live in herd system like what the OLF thinks. The Amhara were subjected to exploitation to the Solomon Dynasty as were the Tigres, Afars, Irobs, Kunamas, Oromos, etc. Not all Amhara or Tigre are entitled to claim they have lineage in the Solomonic Dynasty. It exclusively belongs to those families from whom the last 252 kings of Ethiopia came from .It is clear as crystal like not all Jews were not entitled to be Khan or Kings. People have wake-up. These deviant mercenary sub-sets are vultures they are eating and hacking out the true history of the country. Instead of taking pride, what they are bequeathed with, they are hallucinating about their phantoms while interestingly, the world is venerating the historical relics of Ethiopia. The case in point, the complete Bible of Christianity and other Holy Scriptures only found to be in Ethiopia - the ancient birth place of humanity and religion.
