Jonathan Edelstein has an important post:

The rights of any minority should include opting out of that minority without penalty, and maintaining a traditional identity is a personal choice that the government should neither discourage nor encourage.

Similarly, the problem I have with governments officials interacting with self-appointed "community leaders" is that there are policies that emerge out of this interaction that often result in the creation of the need for "community leaders." Reality dictates that we acknowledge that humans coalesce into groups based on blood & culture, but a liberal order should be cautious of any recognition of this reality because I believe it is fundamentally at tension with this universal, rather, liberalism, broadly speaking, draws from the more generalized communal egalitarianism of the EEA (that is, the government deals with the individual out of the context of their overall "identity").

Addendum: In Suman's post on this in relation to India-which has a political dispute over the "Uniform Civil Code," I made my idealistic pitch in the comments (a function Suman has removed so you can't see them), but I recall Ikram did not believe this was realistic in the context of India. Perhaps the "liberal moment" is God's ephemeral concession to the Hobbesian reality of human history.
