Just because American law guarantees freedom of religion doesn't mean that people will forever cease their efforts to destroy what they do not understand or believe. Joseph Smith, the founder of the Mormon religion, and his brother Hirim were victims of mob violence. First, they were put in jail in Carthage, Illinois. Then they were killed.
After their leader (Joseph Smith) was murdered, Mormons moved to open territory where they could practice their religion without interference. They traveled to Utah. This picture documents their journey in 1846.
Religious practices take all kinds of forms in America. These folks are holding a meeting in a Philadelphia alley in the early 19th century.
The impact of theological correctness in the "old world" was enormously different from its effect in America. The differences stem from the absolute right, established by law, of religious freedom. Without it, those in control impose their will on those who are not. With it, everyone is free to practice one's own religion and, if the right to do that is infringed upon, the law provides a cure.
