You’re completely ignoring the fact that the government not forcing a single church is the separation of church and state being talked about
I never said I wanted to listen to your opinions about the modern state of religion in America. I told you a fact, that church and state are separated by law in this nation and it’s encoded into the bill of rights. That you dislike American culture having evolved from a Christian one is your own axe to grind clearly.
* One nation, under Allah, indivisible… (Islam)
* Marriage is a legal institution between one man any many women (Mormon)
* “The office is closed for Yom Kippur next Monday.” (Judaism)
* The right to bodily autonomy begin at birth so there is no moral issue with abortion (Satanic Temple)
Of course the people are descendants of protestants and so our customs would naturally reflect that but so does our government. As a country we were so concerned about escaping state sponsored religion that we didn’t stop to think at all about how codifying norms into law that come from a particular religion end up creating a religious rule in all but name. Like we don’t even pretend to have religious freedom in any meaningful sense — your right to practice the traditions of your faith or have your institutions respected ends where what is acceptable and normal as defined by Christians ends.
Plural marriage isn't widely practiced or supported for pragmatic reasons.
Holidays are religious artifacts, yet not all of them, and there is no forced participation anymore. (Except in so far as government services are unavailable.)
Abortion rights have and are evolving. As the old, more religious folks die off it should swing the other way soon.
1. A fundamentalist Protestant Christian ethos, derived from the Puritans;
2. A cosmopolitan and secular ethos, derived from British and Western European mercantilism;
3. Literally everything else, including the last 240 years of immigration and infusion by every non-Christian group under the sun.
Whenever people say that America is "Christian," I wonder if they mean it in that syncretic sense, or in an attempt to erase or obscure it.
