Return of prayers in schools? 

All freedom-loving bitcoiners should be against this. 
Religious freedom means being allowed to worship, or not worship, however they wish.  It includes freedom from the rules and dogmas of other people’s religious beliefs so that you can be free to follow the demands of your own conscience, whether they take a religious form or not. Thus, you have both freedom OF religion and freedom FROM religion because they are two sides of the same coin.

TL;DR  Religious liberty depends on being able to refrain from any expression.
