It's less harmful than people think. In a "collaborative filtering" or "chronological timeline with boosts, retweets, etc." world news gets filtered for riling people up and being inflammatory. You might get the conclusion that news itself is a bad thing.
If you subscribed to the RSS feeds of 80 publications and picked articles at random you might find 2-3% of the articles are inflammatory. Filter by personal interests and you might get all kinds of weird stuff but it won't be hateful.
