It's probably because Dominicans in the US don't live in the same areas as Somalis. They're usually found in New York, Chigago, and New Jersey while American Somalis are found in Seattle, Columbus and MinnesotaIs kinda weird how 99 percent of Somalis aren't around Dominicans and vise versa despite having similar mentality. Like you can ask 1 million dominicans in America and all would probably say they never met a somali.
