On the other hand, there is also an inverse correlation between the number of Americans who accept evolution, and violence. An increase in acceptance of evolution over the last few decades has happened as violence has declined strongly.
Sure. Gallup has been asking the same evolution question for decades:
In U.S., Belief in Creationist View of Humans at New Low
As acceptance of evolution grew, so did violent behavior fall. The rise in violent behavior in the 60 was primarily due to the rise of the boomers to young adulthood (when violence is most likely)and the marked decline since the 80s has been largely due to the aging of boomers.
By decade’s end, the homicide rate plunged 42 percent nationwide. Violent crime decreased by one-third. What turned into a precipitous decline started later in some areas and took longer in others. But it happened everywhere: in each region of the country, in cities large and small, in rural and urban areas alike. In the Northeast, which reaped the largest benefits, the homicide rate was halved. Murders plummeted by 75 percent in New York City alone as the city entered the new millennium.
The trend kept ticking downward from there, more slowly and with some fluctuations, to the present day. By virtually any metric, Americans now live in one of the least violent times in the nation’s history.

There's been a small uptick lately, for reasons that shouldn't be a surprise to anyone.
However, the small increase is dwarfed by the huge drop in violence since the 80s.
Sorry, that excuse won't fly. My daughter prayed with her friends in school daily. And it's perfectly legal. If you don't do a good job of teaching your child about God, government is the last entity you want to do it for you.
The good old days when many public schools taught the dominant religion in each community? Let's take a look...
Not very good, was it? No Lon, it wasn't so good. As Madison wrote:
Because experience witnesseth that ecclesiastical establishments, instead of maintaining the purity and efficacy of Religion, have had a contrary operation. During almost fifteen centuries has the legal establishment of Christianity been on trial. What have been its fruits? More or less in all places, pride and indolence in the Clergy, ignorance and servility in the laity, in both, superstition, bigotry and persecution.

As you now realize, in the day when the First Amendment was routinely violated in public schools, violence was much greater than it is today.
