I remember, when I was little, people used to say that males had short hair and females had long hair. I even remember a woman telling her three year old son that, in 2001. One's hair should not be associated with one's gender identity. With someone under the age of about 11, it can be an easy enough mistake to make (if one looks at David Lee Roth in the videoclip of "Just Like Paradise" one can see he's a male, as we can see that he shaves and has the rugged brow of a male. Similarly, with Sinead O'Connor, one can see she's a female). The length of your hair should not be associated with your identity, gender or otherwise. You hair is about you. And I also say that one's identity is one's own to determine.
