Meadow - I am also hairy - I'm part english and part indian but everyone things I'm Iranian. I mix with lots of Iranian women but can't keep up with the epilating thing. I've simply given up. Remain hairy and proud.
In relation to being mixed heritage. First, I'm not black. But I am nearly 50 years old and UK born and I've seen sooooo much.
First thing I would say is that we moved out of London when I was young. I was the only so called 'ethnic minority' at my school. I can pass as a dark skinned white person but in a small community, everyone knew my parents. We're talking 1970's here.
So:
School was super crap - had preconceived ideas and thought I couldn't read /write English. I was written off even though I had a reading age about 3 years in advance. My df was unhappy and complained. It did no good. But I did fine anyway. My df (English) was a lateral thinker and turned every negative into a positive and this helped me loads. He did give me books about mixed heritage issues when I was 11 years old but these were graduate entry books, so I ignored and I was fine - with my parents. Note my Indian mother never gave me any guidance but I was brought up in the centre of a large exended asian family. It all felt normal.
School friends LOVED me as they thought we were different - and it was not cynical - they just hadn't met a family like ours. My mother would never accuse them of racism because of their lack of experience with other cultures.
Beauty - my parents NEVER brought me up to think of beauty in any shape of form (neither did my mother help me with my hairiness) - they were both non racist and non sexist. I grew up in an area where pretty much everyone else was blond - I had a greasy dark olive skin, and had very dark, thick and frizzy hair. . Yes, I did not feel attractive, but my parents viewed me as individual and encouraged me in that and so I was viewed as different and 'cool'. That has stayed with me all my life.
I have a ds who is not of my ethnicities - and he's constantly asked where he's from - he says he's a child and not a nationality - FANTASTIC - so proud of him.
As I said, I'm well into middle age and I really feel that innocence of the past has been lost - that makes me rather sad.
There is no prescriptive idea of being mixed heritage in my view.
There is racism and it must be tackled but there's no one size fits all way of dealing with it.
