I read the DM from cover to cover once when I was on holiday and the local guy had sold out of proper newspapers.
I was aghast, depsite already knowing pretty much what their agenda was. This was years ago - they had a two page spread 'outing' Heather Mills as a former topless model (complete with pics, so we can all see the nasty slutty behaviour) and comment from the feature writer that 'Sir Paul will no doubt be appalled to hear this news'.
Why of course, the ex Beatle has never seen a pair of tits in his life.
I spat feathers for the rest of the holiday although one thing I will say is that they do have quite absorbing features about history, interesting people from the past etc.
As for 'if you don't like it don't buy it', that is the lamest argument ever. Yes, we could all just ignore all the films, telly, books, newspapers etc that don't appeal to us but as humans we are naturally curious and critical. What a banal life it would be if we couldn't actively debate stuff that we don't like.
Christ, why have MN at all, if there's anything you don't like or don't agree with then just ignore it - well, you do that if you like but I prefer to 'question everything', like the wee boy in that advert!
