It's cultural and religious differences, somali's are all muslim and AA's are not, conflict was bound to happen. I also notice ethiopians get along with AA's/blacks easier than somali's because of religious commonality.
Just look at razzberry's topic as an example, she considered those youtube videos about those girls in bikini's innocent, while a somali, usually from the older generation would freak out and call those girls love's.
There needs to be some sort of understanding between both groups, laakin, with all disenfranchised poor people(somalis and AA's, even poor whites), xenophobia and mistrust tends to keep people hating each other.
