The correct answer to this open question is the following.
There are many influences of new immigrant groups on religion in the United States.
Immigrants from Latin American are mostly Catholics, and they profess o full devotion to the teachings of Jesus and the devotion of Mother Mary. Immigrants from Asia (China, Japan, Korea) profess diverse eastern religions such as Buddhism or Confucianism. People from Europe follow Protestant religious teachings, meanwhile, people from Africa follow diverse religions of their own communities.
When entering the United States, these people never lose their religious principles, to the opposite, they have them very ingrained in the belief system and as well as their culture and traditions, they live them to the fullest in the US, creating an interesting mixture of belief systems that to some traditionalist people, represents a risk to the American culture.
