Did you miss the part where the opinion section is one section of the paper, and clearly labeled as such. This is a standard practice in newspapers going back centuries. The person you’re responding to was pointing out how much they like that the rest of the paper reads as quite factual. That’s the mark of a good paper, keeping the opinions on the opinion page. (I can’t attest to whether the WSJ meets this standard, as I don’t read it, but I’ve heard this said of it more than once.)
See my post above this. There is no objective section of the paper. Give me one example of an article they posted that isn't an opinion piece.
