Interesting cites Frederick. I am curious about the context that Dr. Pianka was addressing and advocating mass extermination? 

As far as Tom Metzger, he was found guilty and there was ample evidence that he incited the murder. Of course, I think he should also be doing some time in the crossbar hotel as well. That is just my opinion. 

I can understand the feelings of the time considering the actions the Third Reich took in exterminating a few million jews. Maybe the decision was justified, maybe not. I am in no position to judge. However, Julius Streicher was part of the Nazi war and propaganda machine.

As always, an interesting and educational exchange. Thank you, kind sir.
