Religious oppression was one reason many of our ancestors came to America. They wanted to escape rulers who demanded that everyone worship their way. In Ireland, Catholics couldn't vote or own a gun. John Stossel assumed that because many of America's founders came here to escape such repression, they were eager to allow religious freedom in America. After all, the very First Amendment in the Bill of Rights says, "Congress shall make no law respecting an establishment of religion." But, writes Stossel, he was wrong.
