Glenn Greenwald brings exceptional rationalism to times that are infested with fear mongering. Because fear makes people stupid- It makes us unable to think straight. & it makes us give up our power to tough-talking authoritarians
John Adams, in his 1776 Thoughts on Government, put it this way:
Fear is the foundation of most governments; but it is so sordid and brutal a passion, and renders men in whose breasts it predominates so stupid and miserable, that Americans will not be likely to approve of any political institution which is founded on it.
