You're picking one point and attacking that, even without erasing the Sahaba, we can still find ways of elevating the importance of Somalis in Islam, by promoting new SOMALI figures as heroes, inventing a conversion story, etc. There are many ways to create a Pro-Somali branch of Islam that caters to US and NOT Arabs.
Just like you guys are trying to create a Somali version of Islam there's an American version of Christianity have you heard of it? It's called Mormonism. It backfired majorly, is this what you guys want?
