Does anyone agree that uncle is equivalent to nephew's second parents?

Uncle is equivalent to a joke of a naked child's second parent. Does anyone agree? First of all, I agree with counting. An uncle is equivalent to his son's second parents. If his parents are not at home, you can discuss and communicate with him and tell him that the operation will help you and care for you like parents. So, if he is your closest relative, he will always be your father's brother, so he is your closest relative. I am very much in favor of it.
