"Truly American"
At the Public Religion Research Institute, Maxine Najle and Robert P. Jones report on survey data:
When asked how important certain characteristics or beliefs are to being “truly American,” Americans overwhelmingly agree that a few characteristics are fundamental to being American, but are more divided on others. The vast majority of Americans agree that believing in individual freedoms, such as freedom of speech (91%), respecting American political institutions and laws (90%), accepting people of diverse racial and religious backgrounds (86%), and being able to speak English (83%) are somewhat or very important to being American.
Americans are more divided on other characteristics. A majority (56%) of Americans agree that believing that capitalism is the best economic system is somewhat or very important for being truly American, while 38% say this is not too important or not at all important. A slim majority (52%) of Americans agree that believing in God is somewhat or very important for being American. However, only 39% say that being a Christian is somewhat or very important for being truly American, while a majority (56%) say it is not too important or not at all important.
Half (50%) of Americans say that being born in America is somewhat or very important for being truly American, while 46% say this is not too important or not at all important. However, Americans decisively reject the notion that Western heritage is fundamental to a truly American identity: only 17% say that being of Western heritage is somewhat or very important for being American, while most (78%) agree that this is not very important or not at all important.
