Seeing as you filthy heathen blasphemers have not consulted the book of all answers, then here is the definitive, absolute, final answer to this age old question.
From 1 Corinthians 11:14 (New International Version)
"Does not the very nature of things teach you that if a man has long hair, it is a disgrace to him?"
And now that I have settled this issue once and for all I expect this thread to be closed forthwith, or, I dunno... tornadoes or something.
And before any of you fornicating sinners bring up Jesus? long hair...
That was a wig.
And don?t ask me why he was wearing it, that's a complex theological mystery beyond your understanding, that?s my story and I?m sticking with it.
Yours in the flying Spaghetti Monster.
