Nonobservant Jews, motivated not by Judaism as a religion but by the secular Jewish tradition of social activism, made up the largest group among college-age whites who volunteered in the South during the dangerous summers between 1960 and 1965. Nigger was the only epithet hurled more frequently at marchers than kike and Jew-boy. Goodman and Schwerner espoused the secular humanism that motivated so many of the young Jewish volunteers.
... Schwerner was an atheist and a humanist who, his wife later told interviewers, believed in all men rather than in one God.
... Goodman was a product of the same secular Jewish tradition; like Schwerner, he declined to have a bar mitzvah.
... To me, a good Jew is someone who believes in the equality of human beings and reaches out to those in need. That’s what Andy believed—and that’s why he went to Mississippi. Not because God told him to do it but because he believed in human beings helping other human beings.”
