Wiki on the gruniard.
May not always be right but I am sure someone here would have corrected the entry by now if it was inaccurate.

The paper's readership is generally on the mainstream left of British political opinion. The newspaper's reputation as a platform for liberal and left-wing editorial has led to the use of the "Guardian reader" and "Guardianista" as often (but not always) pejorative epithets for those of left-leaning or politically correct tendencies.

The extreme left here may think the gruniard is center but the rest of humanity, barring Donuel, accepts it is a leftist rag.

Even more of you in denial. Is it contagious?
