While a constitutional regime can fully ensure rights and liberties for all permissible doctrines, and therefore protect our freedom and security, a democracy necessarily requires that, as one equal citizen among others, each of us accept the obligations of legitimate law. While no one is expected to put his or her religious or nonreligious doctrine in danger, we must each give up forever the hope of changing the constitution so as to establish our religion's hegemony, or of qualifying our obligations so as to ensure its influence and success. To retain such hopes and aims would be inconsistent with the idea of equal basic liberties for all free and equal citizens.
