Contrary to what people would have you believe, the vast majority of non-Somalis barely know what Somalis are. You could literally tell them it's in the Caribbean, and they'll think on it for a second before accepting it as a fact. From personal experience, you won't get free points (except with some non-Somali Black girls) but I'm telling you, at least you'll have a blank slate. The worst they stick on you is the Black man stereotype but that quickly goes out the window if you're somewhat well-spoken, show connection to your roots and some conservativeness. Not to mention most Somalis being Muslim. To a shocking number of people Black and Muslim is mutually exclusive.
I see it that you're not from Canada.
