Real conservatism is not so simple minded, and never has been. Traditionalism is part of conservatism, and an important part. But that is hardly the whole story.
I much prefer Russel Kirk's Ten Conservative Principles to the shallow description of conservatism above.
One of the problems with conservatism today is that it continually attacks "Neo-conservatism," but fails to define it the same way twice. The term originally referred to a clique of predominantly Jewish Democrats from New York who switched their political affiliation to the Republican Party primarily over the issues of strong national defense and anti-communism. These days the term is tossed around to label anyone judged insufficiently conservative - a variable definition, dependent on the frame of reference of the accuser.
