I honestly couldn't give a damn about Somali ex Muslims. There mostly coward munafiqs who stay in the closet and they know they will be outcasts the moment they choose to come at their closets. There's bigger fish to fry like big Islamophobic organizations, the Ex Muslim community, Christian missionaries and the Right wing Islamophobes. Instead of debunking gaal Somalis specifically, you can spread your dawah to the Ex Muslim and others generally.
It must be a big closet from what I’ve seen in here with a ventilation system and three square meals.
