'Oxbridge' is a pormanteau for the University of Oxford and the University of Cambridge in England and the term is now used to refer to them collectively, often with implications of perceived superior social status.
Once you get into Oxbridge the work rate is phenomenal. It is a study marathon and you have to be of a certain type to get through it. If you weaken there are squawks from the hallowed halls; the subtext of which is: - 'Come on, old girl, 'Man up!'
Seen through the Oxbridge prism your academic arguments have to be not just discursive but decisive, conclusive, rigorous, robust and intellectually muscular. Oxbridge is not the place for jouissance or ludic playfulness, nothing epistemologically epicene; none of that kind of 'stuff'.
You have to be a certain type to survive Oxbridge and get through it - the competitiveness combined with 'study stress' can be unbearable and the certain type you have to be is a 'man' for that is what they are essentially looking for. It is enshrined in the Oxbridge appraisal system.
But if we are going to comment on such matters let us at least be rational, reasonable and balanced
(historically male notions) for Oxbridge has been in existence for 800 years and they only admitted women through its portals....when was it now, oh yes, 1920.
