The Old Testament was kept by Masoretic Scribes. They were very very very conservative on how they kept their texts. They would copy the Old Testament scriptures for a living. The King James Bible uses the masoretic text because no one has the originals. Only place you can get original text is the Ark of the Covenant (At least only the Law of Moses and Joshua I believe are in there.)
As for the less hate and fire and brimstone. Just buy any new translation if you want blasphemy. Most take out the damning parts to make it more friendly. They also take out the blood of Christ and his Sacrifice.
So if you want BLASPHEMY buy a NIV Bible, why not buy three. Though if you want the good stuff buy KJV. Also, us fundamentalists will not die out, while world religions have been around, and people have been persecuted for not going with the flow we were there. We may not have been called Baptists, but fundamentalists have always been around even during the time of the Apostles. Also DUmmies, hope your common core reading skills are up to par. NIV requires an 8th grade reading level. KJV only requires a 5th grade reading level.
Remember all the Churches (Corinth, Galatia, Thessalonian) that Paul wrote to? It was because some Liberal was spewing lies about the Gospel, and was injecting poison into the churches, and teaching them false doctrine.
Reason why the Apocrypha is not in the Jewish Canon, or some translations, it was because it was not accepted as Canon. It is also innaccurate. One book called Nebuchadnezzar the king of Assyria. He was the king of Babylon, history proves this, and so does the Old Testament. Apocrypha was introduced into the Catholic church, and suddenly appeared when they were teaching things like Purgatory for the first time. The Original KJV had the Apocrypha because most people believed in it at the time. The only thing you can rely on is the Maccabee books 1&2, but take it with a grain of salt. Eat the meat, spit out the bones. We know Hanukkah is real because it was kept as a Jewish tradition, a story, like Purim. Hanukkah didn't start because of some Catholic book.
