Maybe it's because Wirral tries to turn every thread into an expose about BIDS ASA complaints and uses every mention of a presenter to parade the complaints he has made against them. Maybe that's the reason people think he Loves lcomplaining to the ASA? he certainly features it a lot in his posts. But some people LIKE to complain. It's what keeps them going. Gives them a purpose. My sister calls it 'glass half empty syndrome' people who are born to look for the bad rather than enjoy the good.
My better half (who's American) once said to me that complaining & not taking any BS is something alot of Americans like about the British. I suppose we are a nation of people who don't accept incompetence & we get bee's in our bonnet rather easily... yet usually fully justifiably.
