Your root cause argument I suspect is true: because I value the editorial message I overlook the flaws. In this regard, the News Ltd and Guardian are the same thing: they are newspapers. But, my root position also remains. I chose to give one money and not the other. I should just be more open to the reality behind that decision. The only person I am fooling, is probably myself.
It’s one particularly egregious example but there are plenty more: education is another, why are state comps good enough for The Workers while Graun types go private? Or housing.
Oxford is biassed to private school entry because its competitive. But it is emphatically not closed to state school pupils, and never has been. But in any case, whilst a lot of guardian journalists and columnists went there, I doubt all did by any stretch.
It's left wing, not working class. The sun is working class, tits and all.
