Freedom of religion is not freedom from religion, and the state should actively encourage citizens to have a religion (out of Evangelical Christianity, devout Catholicism, Mormonism, Orthodox Christianity, Orthodox/Hasidic Judaism, and Islam- maybe there are one or two more that I am not familiar with that would do the same social good). For cultural and societal reasons, we should have a vested interest in virtually everyone practicing one of those religions. Other religions and secularism should not be illegal, but they should be highly discouraged verbally by our leaders.
Now, I would encourage everyone to convert to Christianity as a matter of faith, but for societal benefit, any faithful Abrahamic religion provides a solid moral code, and it is more important (not spiritually, but for stopping our moral decay) that people have a religion than which religion.
What a terrifying society that flies in the face of the Constitution.
