Tell me, what is human culture? How do dress if you're supposed to be a human? What do you eat if you're a human? What religion are these humans? I could easily answer those questions if I were talking about my own heritage, but like hell if I have any idea how humans on the other side of the world act. There is no one human culture (just as there is no one English culture). As I said, all cultures are open to you. Why on earth restrict yourself to one or two?
