Texas lawmaker: I want Christian chaplains in schools to "put God back in government"

Forcing a specific religion on people does destabiize the state, especially if the state religion is at risk of changing every time the regent monarch changes.
Republicans who want to instill a state religion cannot stop at Christianity, but will have to narrow it down to a specific ministry criminalizing the rest.
If their effort doesn't drive the nation to bloody social unrest, the purges of heretics will be even bloodier.
That said, in the aftermath of the Christian Nationalist movement in the US, Evangelist Christians will be regarded much like nazis in the 1950s. And those eager to hunt will be glad to confuse other Christians for nationalists if they're desperate for game.
