Here is a short piece of mine published on Lib Dem Voice. In it I argue that Murdoch is part of scrap amongst right-wing newspapers which those of a liberal persuasion can observe without taking sides. It attracted a few comments, but of pretty poor quality. Mainly it was from people who so loath the Murdoch empire that they automatically oppose anything thing he does. Somebody launched a rant against the BBC licence fee.
I have a wider concern. By focusing so much on Mr Murdoch liberals are in danger of losing a bigger and more important argument; they are attacking the messenger rather than the message. It's a sort of displacement activity for people uncomfortable with the right-wing press.
