For 300 years, using the New England Primer, McGuffey Reader, Blue Back Speller, and Holy Bible, the nation's schools taught Christian doctrine pervasively.
Perversely.
The "nation" hasn't existed for 300 years, only 250. Public schools only become relatively wide spread 200 years ago.
States have been incorporating into their constitutions laws against sectarian education from the mid-19th century. I think you are mistaking a few prayers and a bible verse that did exist in the common schools for the kind of pervasive religious education from parochial schools.
That ingrained upon all children a sense of objective moral values, individual responsibility, respect for others, law and order, and eventual judgement before God.
Morals aren't objective. Schools weren't teaching sectarian dogmas about "judgment".
That all changed in the second half of the 20th century with the removal of God, the Bible and prayer from the classrooms.
Good. Never belonged their legally in the first place.
Since the secularization of America's educational system, the number of teen pregnancies, teen suicides, and school shootings have skyrocketed.
We can check some of these correlations, and teen pregnancy rates are *higher* in states with more church attendance and self described Christians.
The number of Christians have declined each decade as the culture has worsened, and now it's also affecting the churches, pregnancy centers, and outspoken Christian agencies.
So sad. Don't care.
Is this coincidence? I don't think so. I agree that America has to regain it's Christian heritage to solve the cultural problems, but I don't see it happening.
America isn't a Christian nation with a Christian heritage.
We have too many professing Christians siding with the Devil on the nation's sins - advocating a separation of church and state, embracing evolution teaching over creationism and opposing the death penalty while supporting abortion rights, gay marriage, transgender ideology, critical race theory, and other moral relativism values.
1. Church-state separation is part of the founding laws of the United States.
2. Evolution is a successful scientific explanation of Earth's biological organisms. Creationism is religion (See #1.)
3. Executions are Christian? (Shouldn't they be crucifictions if they are?) A few states ended executions before the Civil War (they were, not coincidentally, slave-free states.) There are massive churches who make the same "moral decay" claim against "secularism" that you do and consider executions to be just as immoral as abortion.
4. All morals are relative. Deal with it.
God help America. In the meantime, I'd suggest that CCW's be welcomed in all churches.
I would have never attended a service that welcomed armed people inside God's house.
Most one-time shooters, like career criminals, don't really want to face a gunfight or die.
LOL. A significant fraction of these "one-time shooters" appear to be suicidal. Many shoot themselves or are attempting "suicide by cop". Now, assassins seem to be interested in getting away (Minnesota assassin, Kirk assassin, United Healthcare assassin).
A little more self protection would not only reduce future casualties but might also deter some prospective shooters contemplating the idea.
Nah, they'll just have to plan a little more to ensure their intended "kill count" before they expire.
