I know, I was shocked about the hostility Somalis have against ordinary Habeshas and I thought may be because they are ill informed so I tried to provide factual data even though I am not much successful

Especially hating on ordinary people is something I can't get my head around.
Anyway, Habesha families don't teach their kids to hate Somalis, they never even mention them. My whole relatives, all of them without exception are simply ignorant about Somalia and Somali politics let alone to hate them. They are sometimes surprised when I explain them the different between Somalia and Somaliland or that our Army is still in Somalia etc. They just don't have a clue even those who are very informed about Ethiopian internal politics. And the Adal wars, Habeshas see it just as a civil war between Muslim and Christian Ethiopians. They never associate it with Somalis.
