Your Constitution requires that the secular world and the religious world be kept separate. Your nation was founded by Protestants fleeing the religious violence and persecution of the Reformation.
The USA was founded as the Spanish Inquisition was still ongoing. Virtually all of the wars of the last 2000 years in Europe, have some religious component to them. The Catholic Church has been intimately involved with European monarchs and governments since it's founding, and not for the betterment of humanity, but in order to preserve their own wealth and power.
Your Founders did not want religious wars or religious influence on their government. Now you have a large faction of ultra right wing CATHOLICS, which want to take over the US government. They've got the Supreme Court (6 of the nine justices are Catholic), and now they're going for the White House.
