Use a straw man. Find or create a seeming element of your opponent's argument which you can easily knock down to make yourself look good and the opponent to look bad. Either make up an issue you may safely imply exists based on your interpretation of the opponent/opponent arguments/situation, or select the weakest aspect of the weakest charges. Amplify their significance and destroy them in a way which appears to debunk all the charges, real and fabricated alike, while actually avoiding discussion of the real issues.
Oh look, another straw man
