You sound very much like the folks a whole bunch of us went overseas to fight for the last 15 years. Using religion as a guiding compass over the last 1000 years has worked really well for them.
In a lot of ways, you have been getting what you wanted for the last 30 years or so, which was about the time one of our political parties sold itself to the religious-right, and has pretty much been shaping policy since.
Sorry progress backward to 1958 has been so slow, but don't fret Marty McFly, the current administration more than wants to hop in that garbage powered Delorean right next to you. Before you know it we will be right back in 1958, where Ms. Parks new her place was on the back of the bus, the good Christian men that lynched the Till boy can be acquitted and writers, artists and (gasp!) homosexuals can be labeled commies and made enemies of the people. Good times.
You're right though, there may have been a bit more Jesus in the water in 1958, and a complete absence of mass shootings in schools with AR-15's type rifles, though I would counter that is less about god and more about the fact that the M14 wasn't around until 1961 and M16 A1 didn't roll out until 1968. About the closest thing a young guy had to shoot up his schoolmates at a high rate of speed with was the Thompson submachine gun, but that had pretty much been regulated out of civilians hands in 1934 with the National Firearms Act. Shockingly enough, mass death by Tommy gun plummeted after that, unless of course you were a group of Japanese soldiers in Burma and on the receiving end of a gun that was clearly meant for the military and not for civilians.
