If what Andy Gray said off air was so heinous (rather than just rude, unpleasant and boorish - which it was) that it merits dismissal regardless of his eminent public position, then the fact that his private comments were later leaked is irrelevant and we should at all times and relentlessly pursue all who say (or believe) anything like it - and not just about women - right down to the man who wipes Murdoch's arse for him. (Spend a second or two to think of the possible consequences of that, by the way. The effects on the number of people hounded from employment, I mean; not those of wiping Murdoch's arse, though they are doubtless preferable to those of not wiping it.)
If, however, the problem is just that Gray's comments were, by whatever means, broadcast to the public, then those who believe this actually demean the case against his kind of casual sexism, since his only offence was being found out.
The trouble is, many of those I have heard on the radio tend to hold both views at the same time. I'm not sure that you can.
As for Murdoch and his companies, they are a morally neutral zone whose sole purpose is the generation of profit. We shouldn't forget that, less still congratulate Sky for their supposed backbone.
