I do not think that the best use of government is to enforce one religion or culture over another religion or culture.
That smacks of bigotry.
The best government is that which governs least.
Let religious views be debated in the marketplace of ideas, among those who care to do such.
Let people celebrate their religion and culture or lack of religion and lack of culture as they see fit.
I don’t want to enforce my personal beliefs and personal preferences on you, because under a different government, that would permit you to enforce your personal beliefs and personal preferences on me.
To the extent that this has been done in the past, it is an injustice, antithetical to most notions of individual freedom.
The only equitable solution is that no one should be allowed to enforce their personal beliefs and personal preferences on anyone else.
Stated in another way:
Do unto others as you would have them do unto you.
You don’t have to reinvent the wheel.
