Sounds like Americans vs.... Americans.
And it's been that way since the inception of this country. The United States of America has a long history of marginalizing people who aren't of the Christian faith and who aren't White people.
For example...
(1) For 188 years in the United States, Black people and other minorities were racially oppressed, subjugated, segregated, discriminated against and denied equality to white people.
(2) For 89 years in the United States, slavery was legal and Black people were considered to be inferior to white people. From 1776 to 1865 slavery was legal in the United States.
(3) For 99 years after slavery was finally abolished in the United States, the descendants of the freed slaves were then denied equality to white people and they were legally segregated from white people until the Civil Rights Movement in 1964.
(4) For 89 years in the United States, Black people were denied the right to vote (despite the Thirteenth Amendment) until the Jim Crow Laws were abolished by the Voting Rights Act in 1965.
(5) For 148 years in the United States, Native Americans were denied United States citizenship until the American Indian Citizenship Act in 1924.
(6) For 202 years in the United States, Native Americans were denied religious freedom until the American Indian Religious Freedom Act in 1978. Native American religious dances such as the Ghost Dance and the Sun Dance were both illegal and punishable by imprisonment.
(7) For 214 years in the United States, Native American religious sacred sites and burial grounds where the remains of their ancestors and family lie could be desecrated and destroyed until the Native American Graves Protection and Repatriation Act in 1990.
(8) It has been an ongoing struggle and battle for LGBT American citizens to obtain
civil rights and equality and it has been an uphill battle for them to fight against religious-based discrimination.
There are specific reasons why a multitude of
civil rights groups and
social justice groups exist in the United States, despite being supposedly founded upon freedom, liberty and justice for all.
