For too long, humanity has been plauged with an abusrd question...why is a Grapefruit called a GRAPEfruit, if a Grape ia already a fruit? And to boot, while they have similar growing patterns, they do not taste nor look any similar to their purple, tiny, SWEET counterparts. So, I say we call it a Tangfruit, as the name is a lot more fitting... (Aka, I wanna win an argument).
