What right is being violated if Christianity is made as the official religion for the Us.?

If Christianity were made the official religion of the United States, it would violate the First Amendment of the Constitution, which guarantees the freedom of religion and prohibits the establishment of a national religion. This would restrict the rights of individuals to practice their own faiths or to choose no religion at all, undermining the principle of religious pluralism. Additionally, it could lead to discrimination against non-Christians and create an environment of exclusion and inequality.
