The most insane thing to me is at the core of the alleged argument for why all of this is necessary, is simply a demand of "freedom of religion" (at least when ignoring the quiet parts that are at the core of that, and aren't even that quite anymore).
Not religious freedom and definitely not freedom from religion (separation of church and state) bc even saying that is somehow an attack on "freedom of religion." If somebody started demanding we all follow sharia law and made sure kids know what's in the quran, the same people demanding freedom of religion, would definitely be freaking the fuck out.
Since we're a "Christian nation," it's what the forefathers intended. That's not true, but if you say it enough times, insist that it was at one point, and claim all you're trying to do now is return America to a place of these traditional values (a place that never existed), you can use this prefigurative traditionalism to force the country to accept any values you want.
Freedom of religion also works to give Christianity the same rights as any person (and more bc you really can't go against God). Kinda like how it turns out corporations were people the whole time, we just didn't realize it until the supreme court made sure we knew.
