There is a very good reason the Founders did not put a state church provision into the Constitution.Now that depends. You see it is possible for their to be a state religion that is serious and it does have favoritism but it still tolerates and allows other faiths to be worshipped. In fact that is historically how most multi cultural/ethnic empires did things. That way allows minority religious groups to follow their own rules as long as they don't cause trouble to the government and pay their taxes. So it is possible for Christianity to become a state religion and then offer tolerance to Muslims, Buddhists, Jews, Mormons, and Sikhs, and other religions that aren't satanic or blaspheming Christianity.
It doesn't matter what other countries have done with state churches, the US was purposely designed not to have a state church.
If they want to use America's flawed past to justify removing rights and freedoms we have now, they do not deserve to call themselves patriots or say they have the best interest of America in mind.I mean yes and no. Early America did discriminate against Catholics, and Mormons and non protestants. Also early Americans said all men were equal, they did not always keep to it faithfully. But now in the modern day if a super conservative decided to take away a right from women people would say that they are violating the constitution even though the constitution itself, or the framers ever said anything about women or all humans. They used the term men. People who don't interpret the constitution strictly and give us our rights, don't deserve to be protected by it. You can interpret freedom of religion the same way Europe does with freedom of speech. Many people say that our allies in western Europe our free countries with freedom of speech, and religion. So why can't conservatives use an interpretation that is favorable to us but not favorable to the left? After all the left will tear apart the constitution to hurt us.
They also then have no ground to complain or bitch about the Left's cancel culture or actions at all.
They can also kiss moderate support goodbye, they can kiss political power goodbye forever, and would be giving the Left a fucking gift they never dreamed would happen.
This is my problem with some many religious groups and their fundies; they are so focused on trying to recreate the past that they cannot adapt to the modern times or the reality of what we need to have a future off this single ball of rock.
We need more Carl Sagans, and fewer scripture driven fundies, making policy or engaging in activism on the Right.
