Wisest Approach

I had gone to the local library website and was checking on what books needed to be returned, when I came across the new Ann Coulter book, "Adios, America".  I read the snippet and the reviews and was intrigued.  But then it occurred to me.  What would be the wisest approach to reading this sort of hyper political/cultural commentary?  As is the case with reading, when we read someone who is "inside our circle", we tend to lower our guards and believe what we read, simply because we are reading something with which we probably already agree.
And the opposite is true when we are reading from someone who is "outside our circle".  We are extremely guarded and critical.  The real chore is to be guarded and critical with everything we read.
So what is the best way to approach this sort of reading?  I cannot say to what degree I agree with Ann Coulter.  Since becoming Orthodox, I have found that within the church, there is not political party.  Some of what the Republicans say is correct, some of what the Democrats say is correct, some of the Third party candidates speak the truth.  But none of them can be whole-heartedly embraced as "the answer" to America's problems.
The real answer, I believe, is that faithfulness to Christ, love of God and love of neighbor, in whatever way we can, is the answer to America's problems.  Reading the various political perspectives and opinions may be helpful, may be harmful, but overall should be done carefully and critically, no matter who you read.  Read with an open mind but filter is all through Jesus' words, "love God and love neighbor".
