Freedom of Religion means that you can both practice (or not) the religion of your choice AND be free from being forced to practice a state religion.
Eugenics, forced sterilization, & forced abortion by the state exist (and have existed in the US).
When you do that, when laws are sliced one way to protect your specific belief, those are called Decrees. And it is not the basis of a free society.
You protect yourself by protecting others.
