Did you read any of my sources?
The BBC doesn't outright say red is blue, because they're not idiots and their target audience aren't idiots, but to state they're not comparable flies in the face of reason. They have shown on multiple occasions to push agendas, to the point that the criticism page on Wikipedia is huge. They are not the bastion of good journalism that they're held up to be by the general public.
The Guardian has it's flaws too of course but that is a far far better source than the BBC. It doesn't claim to be unbias, it doesn't lie to you that you'll hear fair and even coverage from "both sides", it doesn't give preferential treatment to the ruling party in government because of fears its funding will be removed.
Edit: What's scarier? An obvious bias source screaming nonsense 24/7 or a supposed unbias source subtly distorting facts when it suits them? Which will have more influence on public perception? Which is a better propaganda machine?
