This is the plan!! Remember the ስልጤs kicked out the Arabs from Merkato. The Arabs are waiting to revenge on that no matter why the ስልጤ did it ስልጤ have to be punished to stop others do what silte did to Arabs. And that is why they used birhanu to isolate them from the rest of Ethiopians. The ferenjis believe when they kick out ስልጤs from their lands no one will feel sorry for them or protect them because birhanu is abusing Ethiopians.
This is the mind game they played in other African countries
