I hate to say it, but, when people in the "Church", are actually worried about shoulder length hair, on a man, etc...are they really getting what being a Christian is all about?
I fear far more--spiritually speaking--for the person, who is hung up on long hair or clothing styles (I'm not talking modesty), than I do about those who are wearing such.
With so many issues of the day, post-modern thought, man centered righteousness, the elect still in need of a clear gospel message, etc.; for someone to actually focus on the length of hair...seems like they are missing it!
In my study of the Emergent Churches, I find error after error, but it is the very fact, that people can and will be judged for hair length, that those movements have been born. When the Church becomes a place of rote ritual, and rules about hair, it's no wonder, they want to re-invent it.
Let's keep it real, let's keep it about Jesus, the Holy God, King of Kings...let's keep it about sound doctrine...hair length is not what it's about...really sad actually.
