Hi 3mum, thanks for posting 
That's part of the problem of the whole fetishizing thing. I'm in danger of derailing my own thread here, but it's an interesting topic of race and assumptions and acceptance...
I don't give a crap about my race to be honest, I don't feel it is a part of my identity at all, I find it incredibly boring and no more significant than having brown eyes or blue eyes. But I do feel like people want it to mean way more than I do, (hey maybe that offensive group therapy leader when I was 16 was right after all, even though she just bluntly said I stand out like a sore thumb and then didn't bother to lead any further discussion on it). Sometimes they are sinister, sometimes they think they are well-meaning but are just patronising and ignorant, either way it's a bit shitty.
When I was young, my race was undesirable, and the whole spectrum of black, white and asian was quick to point out my physical inadequacies. I live in a very multicultural area but there were very few people who looked like me when I was younger, and when you're in a pack, people always pick on the one who has obvious differences to make themselves feel stronger and superior.
I'm mixed race but I don't fit into the image of what people want me to be. I'm not uber-pretty, I'm dumpy and bookish, I'm not the cool urban friend, I'm a bit dorky...I don't fit the stereotype so I can't be of use to them. If I looked like Beyonce or Rihanna or someone else beautiful I'm sure I wouldn't have had these problems, so it's not as simple as "people think brown people are ugly". But you are definitely measured against different standards. People (twats who I have no time for, granted, but people nonetheless) say straight up that they judge people who different or a minority more harshly. Look at those poor women who were turned away from that wanky nightclub this week - it's so depressing that this kind of thing still goes on in 2015. They've done nothing wrong, and yes the club promoter was the one totally in the wrong, but I wonder who will be the ones left questioning their place on this earth? In my experience it's rarely the perpetrator...
There are loads of studies and evidence on this - if you're in the majority, you can easily coast by being just average, if you're in the minority, you have to be exceptional and work twice as hard to be accepted and given a chance, let alone succeed. And if you are given a chance and you fail, the problem compounds and people think "Yep, I was proved right". You see it all the time with race, with gender, with disability... So I am by no means alone, but I think it has contributed, and I definitely feel it on a personal level.
It doesn't even have to be overt BNP style ranting, the amount of casual offensive comments I observe are depressing. When I was at uni my housemates were laughing about "chavvy single mums with their chavvy mixed raced babies, hahahaha". And these are middle class, privately educated supposedly liberal young people! That they find that kind of thing funny is bad enough, but that they find it appropriate to make a joke about it knowing I was once a mixed race baby, and my mum is a single mum just made me feel a hot sense of shame rising inside me. Challenge it and they say "oh not you, of course" or "it's just banter", but that doesn't soften the blow, somehow... Challenge it more and you can't take a joke and have a chip on your shoulder, apparently.
You can even disappoint people with really basic stuff. I've had conversations like "where are you from?" can be a bit annoying. "Where are you from?" "Luton". "No, where are you from originally?" "Oh, well I was born in Southampton..." "You know what I mean, don't be so obtuse and try to make me out to be a fool!". Or "Are you Brazilian?" "No, I'm from Slough" "Oh...[exits stage right, disappointed]". There was a lot of head-tilting by other girls at school, saying I was "unsure of my identity" because I didn't like urban music, ha. I manage to annoy or offend people just by not being the exotic or cool thing they assume I might be. I tried to be accommodating to people like this but these days I'm so jaded I just roll my eyes when it happens.
Yes the people with the negative/offensive/discriminatory/stererotypical pigeonholing views are the ones in the wrong, but I can't go as far to say "well it's their problem", because it's my problem, because I am the one who feels like shit at the end of their barbed comments, and I am the one that is not given opportunities, while they go about their day feeling superior.
I do agree with you though, that things aren't as bleak these days, and if I were a young person now I don't think I would have had nearly as much of this nonsense. Nowadays I see little girls who look just like mini versions of me all the time, and there are way more role models and so on, so I hope it's getting less of a thing.
Like I said I don't think this is the root cause of all my problems by any means (though I can't deny it is a problem in how people see me, not least because they have explicitly told me it is part of how they judge me negatively, when I was 5, when I was a teen, in my 20s, even last year). But it's an interesting discussion and I know I'm not the only person who feels this way to various degrees, whether it's about race or any other marker - accents, a woman with short hair, someone who gets patronising, pitying "aw bless" looks because of a disability... I should start a tumblr page on it, ha.
