I may not be a conspiracy nut, but I have no doubt there are those who view the Ebola threat as a means to trim the human "disease" on this planet. These are people with self-absorbed lives who believe the pathway to Utopia is where humans will infect Mother Earth with the least amount of impact. These are self-centered people who will use government to minimize the impact of other people and see population control as the way to do it. To them abortion is good and the minimal population is the ideal. That is why I call them the Culture of Death.
