Interesting. I could have applied to Oxford but it wasn't something I felt like doing so didn't. All the other black/mixed people at my uni had AAA/good GCSEs. I definitely think many of us don't particulary want to be out of our comfort zone, so apply to uni's where we're able to be with people who are culturally alike- while getting a excellent education at some other top tier university.
That said, racism isn't about name calling, stringing black people up to a tree and shouting "dirty gollywog" at any given opportunity. Racism is subtle and so prevailent in this country despite what YOU think. Most of you people on this thread are so niave and will never ever understand the 'black experience' or racism in this country. Its because of this whishy washy attitude that black boys are 5 times more likely to be excluded from school, why ethnic minorities are more unlikely to be called in for an interview if they're name is 'foreign sounding', or why BME people are less likely to be promoted in a role. All of this has been proven to be discrimination, so please don't come back with "oh maybe they weren't good for the role". Why not find the root cause and deal with it. It's like you can't accept that black people are discrminated hugely in almost every sector of society. You hold this kind of "oh I hate the way they always scream racism" attitude, and then wonder why you walk into any given school/uni/college and wonder why all the BME people stay together and are untrusting of white people.
Now I'm no racist, I think we need to open up our eyes and see how British society is.
At least America has the guts to challenge things, and accept that racism is alive and kicking- and take pragmatic steps to make things better.
