This thread is quite something.
Black children should follow the rules just like any other child so if there is a rule about no "big" hair styles (white girls can have big hair as well you know) then no big hair styles.
My husband is white, I am black. If we both stood in the same spot for a year, his hair would have grown 6 inches down his back. Mine would have grown 6 inches towards the sky. My hair is not now in a “big hair style”. It is my hair as it grows from my head, not styled, just as his is. Any rule that discriminates against my hair vs his is racist.
I hate the idea that Afro hair is a “style”. It is a texture. Furthermore it is not an “extreme” style as a commenter insinuated earlier by placing it in the same bracket as a skin head or coloured hair (not that they are extreme either, frankly).
When Rosa Parks refused to stand up and move on her bus, three other black people complied. By the logic of some on this thread she was in the wrong and hose who complied were doing the right thing... Imagine how that would have changed the course of history.
Quite.
For the record, I’m a 6foot1 black woman, always tallest at school (girls school, Home Counties) and there were never any “blackboard issues”. I also survived without setting my head alight on a Bunsen burner . I even managed an A for a-level Chemistry.
Finally for those in denial about hair- based discrimination against POC take a moment to google “unprofessional hairstyles for women” then google “professional hairstyles for women”. Then have a think about how it feels to be a black woman in Britain sometimes!
