Equating Breitbart and the Guardian shows your bias I'm afraid. Something like the Huffington Post would have been a better comparison.
I didn't really equate them, I just used as them as examples since they'd both already been mentioned. Also, don't you think that suggesting Breitbart is worse than the Guardian might point to your own bias? The Guardian is designed to look less like a tabloid, which gives the appearance of it being more honest - but is it really a less biased source of news? It's very hard to judge such things. I've been reading the…
What elements? If you mean deliberately antagonistic opinion pieces from transphobic feminists (TERFs) then yes you're right. But I'm guessing that's probably not what you were referring to. If you mean run of the mill socialists then I can't see any truth to your claim - there's a small handful now and it's mostly the same small handful they published 10 years ago (Monbiot, Jones, previously Milne, and a couple of others). The Guardian as an institution hates socialism, even if it occasionally allows a mild opinion piece from a socialist about how it might be nice to raise the top rate of tax by 1% to pay for hospitals.
Other than an increase in the amount of clickbait the Guardian is mostly the same as it was 10 or 20 years ago. The editorial position has actually shifted to the right slightly since Viner took over. But historically it's always been a liberal paper. It supported the SDP, has supported the Lib Dems at various times, supported Blair and supported Iraq.
Part of liberalism involves giving voice to any old opinion no matter how dangerous, crazy, offensive or wrong, at least as long as it comes from the elite class and doesn't do anything as gauche as question the property rights of the wealthy middle class readership (coincidentally this leads to great clickbait on a lot of social and religious issues). So that's why you see the Guardian doing things like publishing articles by Ergodan or other fairly repulsive people as well as hosting flamewars over atheism/islam/feminism/cultural appropriation etc. It's not being left wing that leads to any of that. If it was a left wing paper it would contain far fewer articles of that type because the left wing generally doesn't subscribe to a "free market of ideas" like liberals do.
