More on Extinctionism
Fortunately, we now have the specific technology for doing the job right--and it's something that could be done by just one person with the necessary expertise and access to the necessary equipment. Genetically engineered viruses are already being custom-designed for use in "pest" control. These viruses have the advantage of attacking only the target species. To complicate the search for a cure or a vaccine, and as insurance against the possibility that some Humans might be immune to a particular virus, several different viruses could be released (with provision being made for the release of a second round after the generals and the politicians had come out of their shelters). Of course, natural viruses, such as the smallpox virus, that attack only Humans could be used as well.9 (but don't, for goodness' sake, go around saying that you're actually advocating any of this. We can get our message across just as effectively by, for example, campaigning to make it legal to exterminate the Humans.)
These people really are dangerous, but of course, until they do something actually illegal (like, say, trying to make one of those viruses.) I hope to hell that the various intelligence agencies aren't so busy trying to keep track of Islamists and their dinky bomb threats to keep a close watch on people who want to exterminate the entire human species.
