There are many Oromos who identify themselves as Habeshas, especially who grew up speaking Amharic as their first language in urban centers like Addis Ababa etc. For me they are habeshas through and through in all aspects of life like culture, language, religion etc.
This is the sad fact about the Tulama clan especially those from Finfinne. They’ve lost their language and culture and accepted the Amhara way of life.
