The Socratic Method

Megan McArdle using the Socratic method to argue, tu guoque, that if the people calling Bush a Fascist should not be held responsible for any nut case that tried to assassinate him then neither should those applying similarly overheated rhetoric to Obama be held responsible for any one that attempts to use violence Obama. Note how she doesn't try to shout her interlocutor down and allows her to state her own case, and how McArdle uses her interlocutor's own words as much as possible in counter argument.
