Thank you for pointing out that -- if I may use a metaphor -- toxic medicine will not counter an existing intoxication.
Just to be clear, I'm not trying to learn facts by consuming news. Rather, I simply wish to have an opposite sound inspiring me to think "ah! Interesting view -- I may also be able to come up with some alternative view on my own beliefs/writing/work."
In other words, I'm looking for a news source that, combined with easily reachable opinions, easily constructs some "debate 101"-style, try-coming-up-with-different-opinions, practice-backing-up-both-sides material.
It's not really related to learning something from the news, but thanks for warning me against the worse.
