How is the BBC left-wing biased especially after how they've roasted Corbyn?

I don't know where you're dreaming the "for decades" part from, the BBC used to be incredibly right-wing, and it remains firmly pro-establishment even to this day. The more liberal leaning is definitely a recent phenomenon.

Some programs definitely lean left, but there are still plenty that remain right-wing. Overall the network is probably one of the least biased news sources around, especially compared to the newspapers. And when it comes to important coverage (e.g. elections) the BBC have generally been shown to be quite neutral.

Could they improve on that? Obviously their coverage is never going to be perfect. But I think calling the BBC biased when the Murdochopoly is still allowed free reign is rather ridiculous, personally.

Debatable but regardless, the BBC shouldn't be anything. It should be socially neutral and economically neutral. This is an organisation that claims such a degree of impartiality that it doesn't dare call ISIS by one of it's Arabic names because ISIS doesn't like the term and the BBC wouldn't want to offend ISIS. The BBC should take a similar standard of reporting when it comes to domestic politics.

Are you trying to imply the BBC supports ISIS? I can't even...

The BBC has a huge style guide famed and feared in the broadcast world which literally tells their newsreaders and other emissaries how to pronounce the name of every village in Britain. It is hardly evidence of radicalism, political bias, loony leftism or PC wrap up in bubble wrap ism that they should have arrived at a reasoned decision on what to call ISIS.

This is the British state broadcaster which has a responsibility not to undermine the diplomatic relations of the UK. It is certainly not its role to disseminate belligerent propaganda by deliberately calling ISIS, whom we are not after all at war with, a name which may not represent best practice.

Which is the name you would like them to call them and why?

Way to MASSIVELY misrepresent what I said. My point was that the BBC, when it suits itself, in certain areas, decides to be the bastion of impartiality. It should apply those same standards across the board.

Oh ok fair enough though I think it is as impartial as can be expected domestically
