I'll just grab the headlines from google news and skip the commentary.
Then your opinions will be just as knee-jerk and uninformed as those of the people you're berating. The only difference is that you're keeping them to yourself instead of inflicting them on everyone else.
It takes work to keep yourself informed, and since the news media is more interested in advertising revenue than informing the public, that work now has to be done by you (and me, and anyone else who wants to know more than the superficialities of an issue). Sure it's hard and sometimes depressing to wade through the all crap from @bootycakes and friends, but you will almost always find a point or two that you hadn't considered before, or a link to an analysis piece on another site, or maybe a post from an expert in the field that backs up or refutes a claim from the original piece. These are the things that help you understand the nuances of a story, which is what you need before you can claim that you're actually informed.
