I do believe we're making it easy for people to get only the 'news' they agree with, read only the op-ed that spells out their thoughts.
But it's just as easy to tap into voices of dissent, to find views that are radically foreign to one's own. Maybe even easier and less stressful than it was in other ages.
I think blaming the media or age for intellectual laziness and corporate/political disinformation is neither fair nor productive.
