What role if any should the state play in regulating religion?

Basically the question here is should the government promote its own version of religious practice, in this case liberal christianity and islam?
Absolutely not. Let people practice however they see fit. If they wanna be sexist and homophobic, so be it, we should not regulate what people believe or what they are taught in places of worship (short of inciting violence/crime).
I'm skeptical any of you would support doing this outside of the context of cracking down on conservative islam. in reality, we need to treat all religions equally and not interfere in their practice in such an egregious and 1984-esque way.

The governmennt should not regulate religion, but members of government should not leave their faith at the door for policy making- they have to vote in accordance with their faith.

lawmaking should always have a secular justification. if there is only a religious reason for a political decision/vote, then that would be unconstitutional in the US... and i would not want it in a truly secular country.
if a country wants to properly protect minorities and ensure equal treatment of all, allowing religiously based law making would allow the majority religion to persecute minorities and make life inhospitable for nonbelievers. i hesitate to think that you or any other christian would want to live in a country where muslims for example implement religious-based law, but under your belief then that would be permitted.
imho our visions for an ideal government should be universally applicable, not uniquely tailored to the religious or ethnic majority that resides there.

That would not be unconstitutional in the US.  All that the Constitution says is that we can't establish a state religion or require/ban the practice of a certain religion.  It does not say that we are to be a secular society, nor does it say that legislators need to leave their religions at the door.  "Separation of church and state" is even nowhere to be found in the Constitution.  But, the religious clause of the First Amendment is designed to protect religion from the government, not to protect the government from religion.

SCOTUS disagrees with you. see their "Lemon Test." establishment clause does way more than simply prohibit an explicit state religion.
also even if u were right, i hope you'd want to change the law to make us a secular state. otherwise religious minorities would be subject to oppression, and we'd become a de facto theocracy.
