Of course the influence is there, many Oromos were Islamized by Somalis in the last 150 years or so. The weird gatekeeping makes no sense tho. The borana oromos in northern Kenya term for Alindi is benadiri cloth. They never said Oromo invented it.i saw an Oromo on tiktok doing shaash saar. you can not say that's shared culture. alindi guntiino is not shared. dhaanto is not shared.
also me saying talking about other groups wearing our clothing while we don't wear theirs is not bullying. I'm not actively attacking any group. I'm just bringing this up
