The difference between Jeremiah Wright and radical, white evangelical ministers

Ross Douthat and Ezra Klein are arguing about whether Jeremiah Wright's statements are comparable to those of Jerry Falwell, Pat Robertson and John Hagee's. To argue that they're not comparable, Douthat -- like most people commenting on this raging controversy -- conflates two entirely separate analytical issues:

(1) Given their close and long-standing personal relationship, does Wright merit more scrutiny vis-a-vis Obama than white, radical evangelical ministers merit vis-a-vis Republican politicians? and,

(2) Are the statements of white evangelical ministers subjected to the same standards of judgment as those being applied to Wright's statements?

Even if the answer to (1) is "yes," that doesn't change the fact that the answer to (2) is a resounding "no."
