It turns out a long-time TPM Reader (I'll call him RZ to extra-super-double protect his anonymity) was there and he just after leaving the event he wrote in to tell us that at this event the Teabaggers were joined by a squad of LaRouchies.
About the Mengele incident, he writes ...
In response to a question about medical effectiveness research, the gentleman wearing a shirt with President Obama sporting a Hitler mustache called our dean "Dr. Mengele" for suggesting we compare treatments to find those that are effective, safe and better than other medical treatments treatments. The conversation reached a low at that point.
Apparently the Mengele outburst came in response to a question about medical effectiveness research came from a non-Teabag, non-LaRouche sane woman in her 60s.
So I asked RZ, was the Mengele outburst from one of the Teabaggers or one of the LaRouchies?
Definitely Larouche... They are calling the Obama Plan a "Nazi health plan." I couldn't bring myself to take their literature. They made the Teabag crowd look civil.
Sounds like it was quite a special time.
