The deal with long hair doesn't mean people smoke pot. What about cowboys and their hats in Texas? Is that a sin? My hair is long and in a pony tail, but I don't do drugs or drink. If you keep your hair in a pony tail, you're just fine.
I assume you are referring to the article titled "Hair." In it I stated, "... Jerry Rubin ... believes that his long hair was a symbol of his rejection of society and moral living. Now, I'm not implying that every male who wears his hair long has the same intentions, but he is identifying himself with people who do not agree with God's moral law." It is nice to have personal opinions, but God said, "Does not even nature itself teach you that if a man has long hair, it is a dishonor to him?" (I Corinthians 11:14). Personal preference does not change the truth.
