Well I get the idea, but this whole good hair bad hair debate baffles me because my hair is good hair because it is mine. Why on earth do certain people decide that because there blood is mixed that their hair is better but then on the other hand deny their non-black. They claim something that they detest at the same time.
I have a friend who is mixed black and asian, she does not take kindly to being refered to as asian in any context.
For myself, I believe these people reflect their insecurities onto people they deem as not having good hair, and I think alot of black people for some reason buy into this ridiculous comparison.
At the end of the day my life goes on whether I have good hair or bad hair, and lord knows I've had badly behaved hair, nut it's my hair. I'm not watching your hair or your weave or your braids, I'm watcjing mine.
I always believe that if you are going to say something, make it something positive. If you think you have good hair because of the way you take care of it, fair enough, but purely by the accident of your birth, then you got problems!
