Sweet Potato is categorized as a lead role vegetable in the refrigerator's vegetable bin, a group that includes daikon and carrots. This designation marks it as a main dish vegetable, in contrast to the bit player vegetables or condiments. The resulting hierarchy places lead role vegetables in a privileged position and fosters a system of prejudice against the bit players. Sweet Potato exists within this established social structure of the refrigerator. The narrative centers on Gingerman challenging this system by advocating for the rights of the oppressed bit player vegetables, indicating that Sweet Potato is part of the status quo being confronted.
