Dew, I don't think that religion is a lack of freedom. I can do what I like. I have free will. Nobody orders me for example to go to the church or to obey the Ten Commandments or the Chief Commandments of the Church.
But if I want to go to the church (for example
I feel the need to do that because I believe that it is morally good) and somebody prohibits my religion and forbids me to follow religious observances - that's a violation of freedom.
