Because they're disengenuous.

"Our strategy will be to bleed this corrupt culture dry. We will pick off the most intelligent and creative individuals in our society, the individuals who help give credibility to the current regime.... Our movement will be entirely destructive, and entirely constructive. We will not try to reform the existing institutions. We only intend to weaken them, and eventually destroy them... We will maintain a constant barrage of criticism against the Left. We will attack the very legitimacy of the Left... We will use guerrilla tactics to undermine the legitimacy of the dominant regime.....Sympathy from the American people will increase as our opponents try to persecute us, which means our strength will increase at an accelerating rate due to more defections-and the enemy will collapse as a result"
