This little spell is not evidence that I am posh. Evidence that I'm a show-off? Maybe. Evidence that I'm a pretentious prat? Probably. It might even be evidence that I'm a bit good at writing essays on "Rings in Shakespearean Problem Plays". Evidence that I have managed a feat of social climbing which would make Becky Sharp damp-eyed with admiration? Certainly not.
This media obsession with Oxford and Cambridge... creates an atmosphere of misplaced arrogance and grandeur within those institutions, it fuels the perception that we are ruled by an elite, impenetrable, Oxbridge club, and worst of all it intimidates poorer students away from applying to what are seen as alien institutions that only lets in posh kids.
