Freedom allows us to both live out our beliefs and try to convince others to embrace them without the use or threat of physical or legal coercion. That is one of the reasons RP appeals to evangelicals (such as myself), Catholics, atheists, etc. We should welcome debate; heck, I even welcome your efforts to proselytize me. Because most of all I want the truth, not lies or traditions or even my own self-deceptions. That's the world I want to live in -- one of honest and rigorous debate among people of deep convictions.
The role of the federal government is to provide an environment of freedom where such debate can take place, but without getting involved in the debate itself.
