Godwin's Law:

a progressive rhetorical rule to prevent conservatives from identifying and derogating progressive fascistic policies. Its invocation aims to co-opt the debate over judicial activism, increased executive authority, progressive eugenics, national security policy etc.  

Conservatives should not be afraid of the baby babble that is provoked by progressive fools who use it to say 'move along, nothing to see here'. 

Ann Althouse has more. 

UPDATE: and did I mention gun rights and press freedom? The ideology of the progressive left is so fascistic that they dare not suffer comparison with Hitler and Mussolini requiring that they invoke Godwin's Law at very turn. 

Update 2: The NYT corrects themselves sort of.
