I'm sorry but I have to crash here. To lump mohawks - a hairstyle which I rarely if ever see, even at the odd punk rock show or two - in with those other three is completely ridiculous.
If they're banning that big mohawk "fad" they also need to talk to the white guys with Brady Bunch perms and Dylan from 90210 sideburns, because ya know there are sooooo many of those out there right now.
This policy is definitely unfair to blacks.
