Gurage has experienced pressure and centuries of war and pushing from its vast Shawa country and territory. This is 21st century, it is hard to genocide a whole people and bury history of a people. The conflict between Mareko and Gurage is old. Mareko Gurage mixed people just like Kastana Gurage mixed Geda clan. These 2 clans became issue because Tigrays bribed to split some Selta Fools. Selta is essentially Gurage with some Oromo mix. So nobody surprised if Woyanes create some trouble for Gurage in Selta, Mareko and Geda but the issue in Kebena is basically stupid.
Here Mareko culture:
Here is Maskan culture
