But Lucan has the full backing of his parents. His father was the one who sought the judicial review of the school's decision.
Their lawyer argued this week that Lucan was following in the footsteps of Martin Luther King and Kate Sheppard. So ... this battle for the rights of long-haired teens echoes the struggles for equality of race and gender?
Let's forget that this fight is over a hairstyle. Because it's not.
It's really about a principal's principles versus a student's principles.

Yes, your natural Kiwi instinct may be to defend the underdog, back David over Goliath, but let's not pretend this is such a noble cause.
Just think, it's not really that long until Lucan finishes school and he can do whatever he likes with his hair.
