Listen dude I didnt start here so you can feel at home being racist and stupid. Have some shame and spare us your racist comments please.Habash carbeed all have similar googly eyes, your right there is not much difference between them.
Beenta jooji.Shanshis are reer xamar as they are from xamar and live along other xamaris and have the same accent as they all live together but every reer xamar clan has different ancestries although most date back to Yemen some however date back to Persia and no they don't have the same accent as abgaals although it's quite close. Barwanis however are different, they don't speak Somali but barwani asharafs share ancestory with reer xamar asharafs. Barwani are typically originally from places like Oman and some go back to Persia too. For some reason they have a lot of Kenyan influence and their accent sounds sawahili and most see Kenya as their home as appposed to Somalia. Not sure why though ask @HalyeeyQaran
I've recently met a Shia Iranian girl that didn't speak or look Somali. Her parents did speak Somali though. They were late generation barwanis and went back to Iran after the war.
