One point to bear in mind is how disheartening it is to see racism played out in a scenario like...
an African-american woman is fired from her job/made to leave school for wearing her hair natural or in locs.
A white woman doing the same thing is able to do so with impunity.
Yeah I think that's the crux of this here. I also remember Asian people saying when the bindis etc were popular in the UK a while back, people in my community have been called names, laughed at for smelling of curry etc when they wear their traditional clothes, but as soon as a white person wears the trappings of it, that's fine and in all the magazines as the latest look. I think if black and brown people didn't so often get stick for wearing braids etc, there wouldn't be the same complaints when white people do it.
It is a different context in the UK to the US though, that's true. It's not that we don't have racism, but we're living on land where for many of the white people, our ancestors did wear braided hairstyles too.
Lastly, I'd agree about straight hair being seen as more professional, cleaner etc. I am a white person with curly hair and have some experience of that- my natural texture isn't good enough. I've had more compliments on the whole, probably, but it definitely exists and if it's happening to me as a white woman, it's happening to black women. I remember a few years back actually, there was a thread on here with a white woman who had curly hair, and who was told at work to straighten it. There were a shocking number of posters who thought that was acceptable.
