They're calling you out for being stupid. The problems of people in Somalia have very little to do with any American's day to day life.
When my parents told me not to waste food because others were starving in the world I kind of took that reasoning to heart.
You should have thought before just mindlessly agreeing with your parents. The food that you don't eat isn't suddenly going to be magically transported to places where people don't have food. The real reason why you shouldn't waste food is because it's wasteful and implies needlessly inefficiency. By reducing inefficiency it may be possible to actually free up resources to help people.
