Absolutely. Opinion pieces in a newspaper are not meant to represent the view of the paper, or even to pretend to be objective; they are by definition opinionated and form an essential part of the public debate.
A lot of people don't seem to understand the concept of opinion pieces and letters from readers.
A good newspaper balances the opinion pieces placed, and will leave out obvious falsehoods.
In the era of online news, opinion sections are blended with news.
Even The Guardian falls prey to this: go to https://www.theguardian.com/. Click the Opinion tab. Click any of the opinion pieces. The primary navigation reverts to having 'News' highlighted.
Worse, in reader/mobile view modes, the label "Opinion" does not show anywhere.
It's not a great app, but the one thing it gets right is behaving quite like a newspaper - even down to navigation to select which of the past 6 days' (plus today's) editions you'd like!
(What it gets really wrong, and refuses to accept is a bug every time I report it, is that when the edition updates at 9am/noon/5pm/midnight if you have an article open it randomly jumps to a completely different article that now occupies the spot on which you clicked to open the initial one.)
I see that Opinion is still highlights in the tabs, it says "Opinion" in orange, and that's on mobile.
The background is pale pink, but that's more subtle.
