Existence of Puritans in America

Isn’t America, the country of freedom, life, and various cultures? Don’t cultures contain just race, but religion? Don’t the Puritans, belong in the category of culture with a strong, more as extreme, faith? I think Puritans are a definite part of America as they are recognized for their important presence in American history. They say the current moralities of the American people are very similar to the Puritans’ characteristics.  After they have arrived to United States in want of freedom of their faith. In addition, they have contributed greatly to the expansion of American colonies. In these colonies, schools, education, economy, and government were developed, although it was ruled under theocracy. 
         Since we the people have been living on the base through now, we have beared those certain moralities of Puritans in our lives. For instance, Puritans have been seeking for their pleasant after-lives through their committed faith. We, present-day Americans, are seeking reward and praise through our every-day work. What now, is the biggest difference between them, and us? I don't think we are so far from them than we think we are. The Puritan roots are still remained, although not full.
