Ebola elicits two kinds of reactions in the US. Some think we are in imminent danger of an Ebola epidemic. Others think Ebola poses absolutely zero danger and that those who think otherwise are kooks.
Nothing can be discussed rationally. Even narrow scientific questions lead to emotionally-charged political arguments. Those who have a different opinion must be maligned.
The big question is whether the Ebola virus can spread by air. Experts say “probably not” but some are cautious. For example, Ebola researcher C. J. Peters says “We just don’t have the data to exclude it.” But people who know absolutely nothing about virology are firmly convinced one way or the other.
