No, there are many different cultures in America. You can't just pick one and make it a true American culture. We have many beliefs and values in America today. We also have many societies which people everyday discuss. American culture is expressed by the people themselves. People choose their own belief, religion, and culture they want to have. This is called multiculturalism. It means people in the US have many different cultures and its true we do. There are many people in the who world who choose different types each day and some have more than one. Common cultures can be shared by Americans in certain ways. There's many cultural activities going on in the world today. Many religions in the world and everyone chooses their own. Sometimes people that are growing up the mothers and fathers choose the religion for their own child but once 18 then the kid can choose their own if they wish. Practices are organized by the cultural industry which decides what gets produced for whom, how often, when, where, at what cost, and to what end. Some people can pick just one culture and keep it but like me I have many as well as others. Lots of activities and practices going on in my culture. America is the greatest place on earth and the best culture known to find. You will find lots of amazing cultures here. Not just one culture can belong to just one American.
