Both sides are 90% opinion 10% fact. We can just see the opinions more clearly in the side we disagree with. Personally I'd much rather subscribe to a news source that just provided the facts, but I don't know of one. I used to read the independent and the telegraph in the UK for a slight-left and slight-right perspective, but they've both drifted further apart in recent years.
I still rate the ABC and SBS (Australian) and the BBC for foreign news. The BBC fell off it's pedestal over Scots independence and brexit pretty badly and the ABC has undergone too much Google-following change to infotainment. SBS is underfunded but has a huge following of ex-patriates who lie both sides of most other economies politics and I suspect keep them honest.
