Neither US political party is Nazi.  The unthinking demonization of &#x27;the enemy&#x27; lies at the heart of this problem.<p>Clearly too many of us have become fond of identifying ourselves through membership in Party X.  Shaping my world view around a political agenda by wholeheartedly embracing their entire platform is unnatural and illogical.  But to take the next step and label nonparty folk as unbelievers and infidels creates a problem that&#x27;s impossible to fix through rational discussion, much less leading to the design of workable policy.  At best it&#x27;s bad policy.<p>But party-based exclusion really isn&#x27;t politics.  It&#x27;s just gangsterism.
