Willow Smith's Mohawk

I don't know if you've seen Willow Smith's (Will Smith's daughter) new hair cut but it is a Mohawk. Why did her parents allow her to do that to herself? I am not a fan of the Mohawk myself. It is offensive to many Native American people and it looks down right ghetto and trashy. I'm a teacher, and when students come into my classroom with that crap in their hair I make them get rid of it:especially if its got goofy colors and spray in it. It is so distracting to other students. What are parents thinking? They might as well tattoo the kid from head to toe. And people wonder why they are criticized when they dress inappropriately or wear inappropriate hair styles: because appearance matters! What do others think about this?
