If you are among those who call the President every dirty name in the book and then respond when criticized about your language that you are just engaged in constructive criticism, then this will not be your favorite diary. I must admit that for some time I have seriously pondered at the dividing line between criticism of the President on the Right, and criticism issued from the Left.
For example, the Right frequently uses rhetoric to accuse and to effect condemnation of the President, while the Left, generally, not absolutely, but generally engage in rhetoric to foster constructive debate on the policies of his administration.
