The text below is from a speech given by president franklin roosevelt about european events in 1937: "it seems to be unfortunately true that the epidemic of world lawlessness is spreading. when an epidemic of physical disease starts to spread, the community approves and joins in a quarantine of the patients in order to protect the health of the community against the spread of the disease." which explains why the majority of americans opposed roosevelt's speech?

Roosevelt promoted U.S. intervention in the European conflict, which went against mainstream support of U.S. isolationism.

Explanation:

The Quarantine Speech, given by U.S. President Franklin D. Roosevelt on October 5, 1937, in Chicago, called for a worldwide quarantine as a better option to the political spirit of American neutrality and non-intervention that was widespread at the moment. The last few years, against Roosevelt´s wishes, Congress had passed the Neutrality Acts. His speech increased America's isolationist stance.
