There is nothing wrong with bias. All media has biases, and those that a required to be unbiased, such as the BBC, end up causing other biases with equality of camera time making every issue a discussion. Which has been well exploited by certain minority views.

What has changed is the mainstream media used to care a lot more about being honest. Now they often couldn't give a toss.

I don't mind media being partisan, it's always been so, and often it's revealing to see the reporting from both sides of an issue, and add the FT's take for the financial slant. I do mind that we're rapidly running out of sources that care about being honest. Murdoch ruined the Times, the Barclay Brothers ruined the Telegraph. Both now far more opinion than news. That's a loss, whatever your politics.
