The Enemy Within
This is a little old but worthwhile. Michael Barone, in his weekly column, wrote an excellent piece on "our covert enemies." They are those within our society that despise Western ideals and espouse moral relativism. His conclusion:
We have always had our covert enemies, but their numbers were few until the 1960s. But then the elite young men who declined to serve in the military during the Vietnam War set out to write a narrative in which they, rather than those who obeyed the call to duty, were the heroes. They have propagated their ideas through the universities, the schools and mainstream media to the point that they are the default assumptions of millions. Our covert enemies don't want the Islamo-fascists to win. But in some corner of their hearts, they would like us to lose.
In his blog he mentioned some criticism of the piece. I think his conclusions are completely valid.
