Does the preacher have the right to have the atheist listen to him, on pain of a felony conviction and jail time if he leaves?
Or does the atheist have the right to walk away?
You did not answer my question. One more time - if you believe the military is correct in silencing the preacher because he is recognizing his faith (not just some general faith) and might offend a sailor who is Muslim, then should the atheist have the right to have the preacher silenced?
Its obvious that you answer this with a question because you know the logical truth.
