At this time, Athens was undergoing social turmoil due to the apparent failure of democracy as an effective form of government, which created a public backlash against anything anti-democratic.
[citation needed] Socrates—the self-described "gadfly" of Athens because of his practice of elenchos (critical interrogation)—was seen by many as anti-democratic and thus a traitor to Athens due to his associations with Critias and Alcibiades (the former a Spartan supported tyrant, the latter a deserter to Sparta) and his frequent praises of the Spartan and Creten governments because of their similarity to many of his philosophical opinions on government.
[6] The prevailing political climate of distrusting anything remotely anti-Athens or anti-democracy coupled with attacks from Socrates's personal enemies led to the philosopher's execution by poison in 399 B.C.E.
Depending on the nature of the thoughts (if they are considered controversial or extreme), the emotional reaction can range from nothing to a highly violent state.
For example, the introduction, passing, and court fight over Proposition 8 in California brought a controversial issue into the public sphere, which resulted in such a drastic change in the political climate of the United States as to produce many protests throughout the nation, some of them violent.
The best-known example of this is the 1948 US presidential election, in which the prediction was that Thomas Dewey would easily defeat Harry Truman.
Major polling organizations, including Gallup and Roper, indicated a landslide victory for Dewey when, in fact, Truman was the victor in a close election and kept the presidency.
