Racial segregation of churches in the United States

Racial segregation of churches in the United States means that some churches will only let people of the same race join them. For example, some churches will only let Black people join them, and others only let white people join them, and so on. This means that people of different races are not allowed in certain churches. This is wrong and is not something that should be happening in our country.
