I would also add regarding long hair.. Paul was a Roman citizen and as such influenced by customs normal in the Roman Empire. He lived during the reign of Caligula, Claudius, and Nero, where behavior, fashions and standards were dictated by imperial court. What was fashionable in the court, entire empire followed. The long hair fashion was disapproved by Caligula, who was bald by age 25 and had very big handicap from it. He did not allowed men with long hair around him or hoovering over him due balding.
When I read Paul with view that it was written by Roman person who acted on it when it was profitable and suitable, I cannot shake negative feeling on him. Additionally, it is rather ridiculous when Paul demanded a justice from the hand of Emperor Nero.
