Not at all. I agree, all newspapers have a bias to some degree.

The Guardian is just the Daily Mail of the left. Also notoriously sloppy when it comes to facts, spelling, etc.

The Guardians bias is basically:

BAD - Big companies, government, tories, rich people, MPs, bankers, anyone in power.

GOOD - The 'oppressed' masses, political correctness, the poor, publishing stolen state secrets etc
