These commitments are added on by tradition or through coercion. This book is testimony to the tenacity of Modernist thinking. For the author, the answer comes through liberal democracy's foundational concept - autonomy.
Autonomy is an essential ingredient of living a good life.
Autonomous citizens make their own choices, think for themselves, think critically about choices, appreciate diversity, and tolerate difference. But some religions remain stubbornly illiberal. The problem begins when liberal autonomy meets head-on with conservative religion. But conservative religion seeks to restrict choice, and these religions are by nature exclusive. Even though such groups may restrict their members' autonomy, liberal democracy cannot restrict these groups' practices, even as they restrict their own members.
