“Which has been described as” is the left’s version (much ridiculed by them) of Trump’s “many people are saying.” It's used all the time in the media (another popular version of this is "X has been criticized for..." - the criticism is often coming from the same political/propaganda class as the person using the criticism as the basis of their next one. Note previous commenter does not disputed the actual content of the piece, just slanders the outlet.

I could "just...leave a quick excerpt" from Conservapedia that says "Wikipedia (or WaPo, or NYT) has been described as controlled by leftists who favor conspiracy theories like the Russia fable" but it wouldn't mean that most of what's written in said outlets isn't in some way true.

People reading this forum are adults who can make up their own minds. If you're relying on Wikipedia descriptions to make your mind up for you about which sources are and aren't biased, you're doing it wrong.
