Hi, bobld!
The whole world, especially the US, must now define what exactly is Freedom of Religion. It must be reworded to Freedom to Choose One's Religion, freedom being synonymous with right. But Freedom or Right of Religion as an organization is a different matter. If you give organized religion unfettered freedom, it will dictate on every aspect of one's life, subvert human rights, undermine the state, mislead people, etc. Freedom of organized religion cannot be constitutionalized because it is against the universally accepted law of the Separation of Church and State. Only individual freedom or right to choose one's religion can be enshrined in the Constitution.
I'm not a lawyer, by the way. I'm just a "graduate" of religion.
