Sometimes it helps knowing a source is biased. Reading National Review, for example, allows you to assume the opinions held are relatively conservative. Reading the Bulwark, you know there is a progressive bent. Proceed with your own thoughtfulness therefore in comparing the two. We as consumers/readers never read an article without bias either.
What seems to have changed, to me at least, is that journalists have shed whatever veil of balance and impartiality they used to wear and have gone full fledged activist, even on the job. As such, their image is no longer of the semi-neutral third party, but just the foot soldier of the enemy's side of the culture war. Once you're there, there's no room for balance, or "tempering bias"; concession to the "enemy" is now disloyalty to your side.
