@Justanotherlurker Your post is very valid and I too appreciate that the term 'cultural appropriation' seems to have grown legs and run off to cause all manner of misunderstanding and chaos.
I don't begrudge anyone braiding their hair or anyone eating food from another culture.
The problem is not necessarily with the real-life tangible end-goal of someone's desire to e.g. eat chips with curry or call a scrambled egg a Spanish omelette or whatever. It is the marginalisation of the minority group that is the problem.
When Kylie Jenner (and it didn't start with her) wears her hair in braids it's praised as fashionable. When Marc Jacobs got his white models to wear their hair in knots and dreads it was a new moment in 'fashion' it was 'wonderful' - when black women going to their regular jobs in their regular lives do this they are considered inappropriate and unprofessional and untidy.
That is fundamentally the problem - white privilege.
I'm all for cultural appropriation and mixing - otherwise I wouldn't even exist. But there are structural problems that prevent minorities from capitalising on their own culture which congratulates white men and white people in general for embracing. Black people expend a lot of mental energy trying to not be 'too black' incase they appear too different and a lot of mental and physical energy changing themselves to fit the 'British' or 'European' ideal. This means in practice means destroying their hair and using bleach to whiten their skin and having plastic surgery to alter their features.
Jamie Oliver has stolen a very well known term in relation to Caribbean food which does not even contain or respect it's critical ingredients and has capitalised on it whilst the black man is still languishing. That's not right. It is patently wrong. It is indefensible. And no comparisons of "well what about 'Old El Paso' not being truly Mexican" will work to change that fact.
The problem is when terms like 'cultural appropriation' take the stage and are granted more time in the spotlight than they deserve - much like the term 'snowflake'. It ignores the base issues. The fact that white people have managed to quite literally dominate the world and push their ideals on us and then sell it back to us as a new-fangled entity and we know it's wrong but we are still unable to speak up about it because we'll be called 'uppity' or 'angry' or other such terms which seek to destroy and negate our lived experience.
It will take generations and generations to change this. I hate that I see little girls with dark skin and afro hair hating themselves because essentially they don't look like how the world would rather they look. When I was a child more than one aunt used to say it's great that I'm so light and could "pass".
This furore over Jamie Oliver is just another case in point. And I frankly, am sick of it.
