While the latter part of your statement is no doubt true, the former is demonstrably false. He *is* a crackpot, as evidenced by the body of your post, and a lethally dangerous one at that...

Yes, but a crackpot with a receptive audience.
It presents an interesting situation. What would a nation do if many thousands (tens of thousands?) of its people are billions-genocidal?
The US military uses “surety” programs to insure that personnel who are involved with nuclear weapons are not “differently-mentally-abled”. As little as using cough syrup or any kind of psycho-reactive drug is enough for them to be suspended for a period of from days to for life.
But there is no surety program for civilians in lines of work that are equally hazardous. Should any person who applauded Dr. Pianka be allowed to work with dangerous pathogens? Certainly not. Nor should they be permitted to have involvement with anything else that could be used as a genocidal tool.
