American Religion. Why are so many alienated from the Church today?

I live in the heart of the Bible belt where “religion” is very strong, but all I see is division amongst the people and denominations. Divisions over ideals, racism and tribalism(in a broad sense) when supposedly they believe in the same God, the God of the Bible.

As Christians they are suppose to overcome these worldly separations but they can barley look each other in the eye anymore. These are common problems in our society today as we feel more and more disconnected with each other but we are commanded to rise above this and not be as the world is.

I want to explore the Decline of the Church in America, Denominations, Why most races have their own church even in the same denomination. Mostly why the Church has not risen above these worldly problems in the US but the Church in other countries is united.
