MJF is the latest in a line, as chronicled by Ann Coulter in "Godless", of Democrat spokesweasels which are in some way deemed to be untouchable due to circumstances.
Max Cleland, The Jersey Girls, War Hero J. Effin Kerry, Christopher Reeves widow, Cindy Sheehan, the list goes on....
MJF is just Cindy Sheehan for a different talking point.
The best way to overcome this "untouchable" factor is to verbally bash the hell out of these people.
You noted, accurately, that Fox = Sheehan. They're both nuts.
