It is off point but lets end it here. The trouble with this nonsense about Joseph is that it gets endlessly circulated through Islamic websites so all sight of its source are lost. Most scholar however agree the notion comes from The History of Joseph the Carpenter an apocryphal text probably written in Egypt in the 5th century and purports to be an extended statement that Mary was a virgin not merely prior to and during the birth of Christ, but throughout her life. It is framed as a biography of Joseph dictated by Jesus, and describes how Joseph, aged 90, following the death of his first wife and already with four sons and two daughters, is given charge of the twelve year old Mary, who lives in his household raising his youngest son James the Less, along with Judas, until she is ready to be married at age 14½. It then paraphrases "James", stopping at the point of Jesus' birth. Joseph's death at the age of 111, attended by angels and asserting the perpetual virginity of Mary, takes up approximately half the story.
In terms of this thread it is simply a distraction designed to defect from consideration of the Aisha incident - that is it is never an argument that something is legitimate because someone else did something similar at some time. If you want to argue that case for deciding whether something is good or bad then do that not just fling in spurious materials.
