Your authors are Liberal hacks writing for Liberal rags about subjects near and dear to the Liberal heart. I did not say brain because Liberals by definition are lacking in this commodity. Not one of them lists any sort of expertise with firearms. The claims made by the authors are in some cases ridiculous.
Oh, my quals? Let's see, the US Army says I am an expert with both M16 rifle and M1911 pistol. I have also trained extensively on an M60 Machine Gun. I have competed in five matches against active duty law enforcement and military personnel. I won one, and placed in the top five in three of the other four. I have also been in a real live shooting fight with real people shooting real bullets at me in particular. Is that expert enough for you?
I would also point out that "expert" in the military is not the be all and end all. I shot 40 out of a possible 40 at ranges from 50 to 450 meters with a rifle, and 50 out of a possible 50 at ranges of 7 to 35 meters with the pistol.
The competitions were far more challenging, and the real life situation even more so, since 2nd place sucks.
Now, about those qualifications of your "sources" and for that matter, you......
That's what I thought.
There are a good many REAL firearms experts on this forum. The reason more of them have yet to respond is probably because they are still laughing at your "experts."

People running, some busted up church pews, and some body bags? Who needs GUTS to look at those pics?

The first photo comes from the Mandalay Bay shooting in Vegas.
My nephew was at that concert, he has quite a story to tell.

Have you ever seen a gunshot victim up close and personal?
If not, STFU.

"When a gunman fires an AR15, a safe, familiar place instantly t***sforms into a hellscape of chaos, destruction,
and mass death,"
is one of the most stupid statements I ever heard on the capability of a 22 caliber, semi-auto rifle.
You'd think the AR15 was a WMD and the bullets had nuclear warheads.

Bleeding heart liberal hypocrites are the most detestable anti-constitution SOBs ever to pollute our society.

Since 1980, just over 1500 people have been k**led in high profile mass shootings,
150 of them were children. And rifles of various types, including the AR15, were used in less than 3% of them.

Jesus did not "enact" the Year of Jubilee when He began His ministry, He began His ministry in the Year of Jubilee.
There's a difference.

Jesus, near the start of his public ministry, quoted a section of Scripture related to the Jubilee. He stated, "The Spirit of the Lord is upon Me; for this reason, He has anointed Me to preach the gospel to the poor . . . to send forth in deliverance those who have been crushed, to proclaim the acceptable year of the Lord" (Luke 4:18 - 19).
Jesus was quoting from Isaiah 61, verses 1 and 2. His reference is a Biblical synonym for this special Biblical period.

As written in Leviticus, God Himself established the Sabbatical years (Shemitah) and the Year of Jubilee,
and this was according to God's calendar, not the Gregorian calendar we use today.

The Gregorian calendar and Pagan Assumptions. Named after pope Gregory XIII who reigned over the Roman Catholic church in the 1500s, The Gregorian calendar is a revision of the Julian calendar, which itself was a revision of the pagan Roman/Greek calendars, and it retains the names of the days of the week and months of the year from pagan Rome and ancient Greece.

On many occasions, the Roman Catholic church departed from the Word of God and created its own theology.
The Catholic Virginian said in 1947: “All of us believe many things in regard to religion that we do not find in the Bible. For example, nowhere in the Bible do we find that Christ or the Apostles ordered that the Sabbath be changed from Saturday to Sunday. We have the commandment of God given to Moses to keep holy the Sabbath Day, that is the 7th day of the week, Saturday. Today most Christians keep Sunday because it has been revealed to us by the Church outside the Bible.”

Constantine was the first so-called “Christian” Roman emperor. Though he did stop much of the persecution of Christians as a whole, he did more to introduce sun worship into Christianity than any before him. including changing also the day of Shabbat (Sabbath) from the 7th day of the week to the 1st.
Historian Paul Johnson details some of this influence: “Constantine was almost certainly a Mithraic, and his triumphal arch, built after his ‘conversion’, testifies to the Sun-god, or ‘unconquered sun’. … Constantine never abandoned sun-worship and kept the sun on his coins. He made Sunday into a day of rest, closing the lawcourts and forbidding all work except agricultural labour” (A History of Christianity, 1976, pp. 67-68).

So, a royal decree to rest and worship on Sunday instead of Saturday was made by the Roman emperor, a sun worshipper. Now, thanks to Constantine, Christians were celebrating on the same day the Mithraics worshipped the sun. This is a blatant example of pagan influence in Christian practices.

Christians, now holding services on the venerable day of the sun, became so confused in their worship that, during the reign of Emperor Julian, Johnson notes: “The Bishop of Troy told Julian he had always prayed secretly to the sun” (p. 67). Thus Christianity took on a major facet of pagan sun worship that lives on today due to Constantine’s influence: worshipping on Sunday.

Anti-Semitism and the rejection of the Sabbath

Surging anti-Semitism in post-apostolic times also played a major role in the change to Sunday. The Council of Laodicea in A.D. 365 decided: “Christians must not judaize by resting on the Sabbath, but must work on that day, rather honouring the Lord’s Day, and, if they can, resting then as Christians. But if any shall be found to be judaizers, let them be anathema from Christ” (Canon XXIX).

So, keeping the Sabbath on Saturday was considered “judaizing,” which was considered a great evil.

Constantine, at the Council of Nicaea in A.D. 325, was reported by the historian Eusebius as saying, “It appeared an unworthy thing that in the celebration of this most holy feast [Passover] we should follow the practice of the Jews … . Let us then have nothing in common with the detestable Jewish crowd.”
