Recently I was having a political discussion with a hard-core right-wing conservative friend, and the topic of a certain newspaper editorial came up. The piece was written by Paul Krugman, who is a hard-core left-wing liberal and avid political commentator. My conservative friend commented: "Oh, I never read his garbage - he's a moron."
This made me think how totally wrong my friend was. Not about being right-wing (a totally different subject for another day), but about avoiding opinion pieces with which he disagrees.
There is no challenge in limiting yourself to reading and listening ONLY to commentary you agree with. Part of the problem with the Internet, where each of us can tailor-fit the content to our own personal tastes, is that it makes it too easy to only visit sites written by those who think like us, and avoid the others. At least old fashioned print media (i.e. "newspapers") made somewhat of an attempt to include a diversity of opinion on their editorial pages.
Everyone interested in politics should actively seek out and read editorials written by the "other" side, for several reasons: First, because it challenges you, forces you to defend your point-of-view, and educates you to what they are thinking, and why they think that way. You say the author is a moron? Good - that makes it easy!
Secondly, it give you ammunition. Now you know ahead of time what silly arguments they will make to defend their wrong-headed ideas, and you can prepare and rehearse your arguments to refute them.
Finally, and most importantly, what if they put forth an argument you cannot refute? What if they are right and you are wrong, and in fact, HAVE been wrong all along? I cannot think of a worse situation than walking around being totally wrong about something.
You say that will never happen? Then you have nothing to lose, and everything to gain, by reading, studying, and contemplating what the other side has to say. Oh and remember: you want them to do the same for YOUR favorable editorials!
