Mainstream americans generally rejected traditional religious values during the 1950s true and false

The correct answer is False.

Mainstream Americans were part of the conformist culture of the 1950's. This conformist culture consisted of men and women getting married, having kids, obtaining a house in the suburbs, and following organized religion (especially different forms of Christianity). The Americans who did not follow organized religion during this time were part of the counterculture (also known as the Beatnik generation).
