I listened to AJ when he appeared on Howard Stern's SatRad show, and he kept the nuttery toned down, but during the HS aftershow (where the producer discusses the behind the scenes action) and they dismissed his nuttery for what it is, many of the phone calls were from AJ supporters literally foaming at the mouth that anyone could dispute AJ's assertions.
9/11 was their prime issue, and as it happens a HS show staffer had gone straight to ground zero immediately after the attacks to volunteer (if you've never heard the HS 9/11 show, look it up - he named OBL pdq) - the AJ myrmidons dismissed out of hand observations by the man on the scene immediately to support their (AJ's) version of events.
The aftershow guys treated the nutjobs as they should - they listened politly and thanked the caller, cut-off the call and wondered aloud about how delusional an individual could be.
