We started out as colonies when in the states it was illegal not to belong to one of the establishment churches. One church or another through history was the one and only state church. We have come a long way since.
I've been warned that people have been trying to stop the free exercise of religion in the public square.
Needs clarification, because it was the churches in the past tried, and did, try and stop the free exercise of religon.

Religion In Colonial America
America wasn’t always a stronghold of religious freedom. More than half a century before the
Pilgrims set sail in the
Mayflower, French Protestants (called Huguenots) established a colony at Fort Caroline near modern-day Jacksonville,
Florida.
The Spanish, who were largely Catholic and occupied much of Florida at the time, slaughtered the Huguenots at Fort Caroline. The Spanish commander wrote the king that he had hanged the settlers for “scattering the odious Lutheran doctrine in these Provinces.”
The
Puritans and Pilgrims arrived in New England in the early 1600s after suffering religious persecution in England. However, the Puritans of
Massachusetts Bay Colony didn’t tolerate any opposing religious views. Catholics,
Quakers and other non-Puritans were banned from the colony.
Roger Williams, a Puritan dissident, was banned from Massachusetts. Williams then moved south and founded
Rhode Island. Rhode Island became the first colony with no established church and the first to grant religious freedom to everyone, including Quakers and Jews.
As Virginia’s governor in 1779,
Thomas Jefferson drafted a bill that would guarantee the religious freedoms of Virginians of all faiths—including those with no faith—but the bill did not pass into law.
Religion was mentioned only once in the U.S.
Constitution. The Constitution prohibits the use of religious tests as qualification for public office. This broke with European tradition by allowing people of any faith (or no faith) to serve in public office in the United States.
