Why is modern (Talmudic) Judaism so different from it's ancient (Bible) counterpart?

Why is modern Judaism so different from it's ancient Hebrew counterpart? It is different because, in practice, you can't follow the ancient Hebrew faith without being forced to embrace a mindset that modern Judaism would consider to be “anti-semitic”. You see, modern Jews pay little regard to moral purity, focusing instead on ethnic heritage. So, even if a Jew is a thief, a liar, an atheist, or a homosexual, that isn't expected to affect the respect everyone is supposed to owe him as a member of God's chosen people.
But the former flies in the face of the religion taught by Moses and the prophets. In such religion, no respect was to be shown to he who, while claiming to be Jewish, would blaspheme God's name with his open immorality. And this is why we find many cases were a righteous Israelite would end up slaying a wicked one: like when Moses caused the death of 3, 000 idol worshiping Israelites (Exodus 32: 27-28); when Phinehas caused the death of an Israelite prince named Zimri (Numbers 25: 7-8); when Joshua caused the death of Achan and his family (Joshua 7: 24-25); When the righteous Israelites killed 25, 000 wicked members of the tribe of Benjamin (Judges 20: 46-48); or when Jehu caused the death of Joram and Ahaziah, kings of Israel and Judah (1 King 19: 16-17, 2 Kings 9: 22-27).
In fact, ancient Hebrew faith was such that the righteous believer would avoid honoring the wicked with a respectful glance, even if the former was the greatest of all Israelite leaders (the very king of Israel! ). As it is written: “And Elisha said unto the king of Israel, What have I to do with thee? get thee to the prophets of thy father, and to the prophets of thy mother. And the king of Israel said unto him, Nay: for the Lord hath called these three kings together, to deliver them into the hand of Moab. And Elisha said, As the Lord of hosts liveth, before whom I stand, surely, were it not that I regard the presence of Jehoshaphat the king of Judah [who is a God fearing man], I would not look toward thee, nor see thee ”- 2 Kings 3: 13-14 (King James version).

“Make of meditating in God’s Law your constant habit, so that the Word of God becomes your second nature. As it has been said: “Let not this book of the Law depart out of thy mouth, but meditate therein day and night, that thou mayest observe and do according to all that is written therein: for then shalt thou make thy way prosperous, and then shalt thou have good success”- Joshua 1: 8, 1599 Geneva Bible”

The message of Reformed Samaritanism

He doesn't understand the message of Reformed Samaritanism, the man who refuses to repent, in order to start living by God's Ten Commandments; the man who refuses to treat his fellow human beings with justice, mercy, and humility; the man who refuses to lend a helping hand to those suffering unjust oppression; he who isn't kind to the children; he who refuses to consider the poor and the elderly; he who sows discord between brothers; between husbands and wives; between parents and sons; the man who flatters God's enemies; nor the man who refuses to treat his neighbour with the same truthfulness, honour and respect he would wish for himself

Is it true that God's Law (Torah) only belongs to ethnic Jews?

The Torah (or Hebrew Scripture) intimates that, regardless of their race, those who obey God’s commandments are properly representing the paradigm of what really means to be a Children of Israel. Who are these peoples? They are the “foreign residents” (or “toshavim”) from among the original seventy nations [of the world] who abandon their old ways in order to become “proselytes” (or “gerim”). How? By starting to do all things according to what God had commanded Moses [upon the two stone tablets].
But from whence do we know that, what Hebrew tradition identifies as the seventy original nations of the World, are also called " Israel"? We know it from Moses, who while addressing the Children of Israel said to them: “Shema Yisrael (Hear oh Israel! )... ” (Exodus 5: 1). In the former passage, the phrase “Shema Yisrael” can validly be translated as “Shem-A Yisrael”, which in ancient Hebrew [where letters also have a numerical value] means, “Name (of the) Seventy [nations of the world]? - Israel! ... ”
And from whence do we know that, doing what God commanded Moses, identifies you as a Children of Israel? We know it from the verse that goes on to say: “Thus THE CHILDREN OF ISRAEL DID ACCORDING TO ALL THAT THE LORD COMMANDED MOSES... ”- Numbers 2: 34. And also in another place: “ACCORDING TO ALL THAT THE LORD HAD COMMANDED MOSES, SO THE CHILDREN OF ISRAEL DID... ”- Exodus 39: 42
And from whence do we know that, from God’s standpoint, all of Israel is comprised of converts (gerim) and foreign residents (Toshavim)? We get it from the Hebrew verse that goes on to say: “The Land [of Israel] must not be sold permanently, because the Land is mine, and YOU [THE CHILDREN OF ISRAEL] ARE TO ME “GERIM” AND TOSHAVIM”- Leviticus 25: 23.
Thus, although ethnic Israel is Torah’s “custodian”, Torah itself doesn’t exclusively belong to them. Rather, it belongs to all who will come and embrace it. And maybe that’s why Torah was given in the wilderness, as the latter didn’t belong to any people in particular, but was rather open to all nations.
Not only that, but Moses himself compared his teaching with both rain water, and dew (“LET MY TEACHING FALL LIKE RAIN, AND MY WORDS DESCEND LIKE DEW, LIKE SHOWERS ON NEW GRASS... ”- Deuteronomy 32: ). Does the rain [of heavens] belongs to any particular kind of grass? [Bear in mind that elsewhere the Scripture compares the whole human race with grass, at it is written: “THE MAN, LIKE GRASS ARE HIS DAYS…. ”- Psalm 103: 15].
In the former verse, the word translated as “The man” is “enosh”, a Hebrew word that literally means “Human being”]. Can any ethnic group claim to own Heaven’s dew? Has there ever be any human being, any land, or any nation upon which rain showers are not allowed to fall? Does anybody has the right to prevent a thirsty person from drinking water coming from the sky?
Not only are the peoples of all nations called to become Israel [by obeying Torah], but if Israel’s former enemies [like Egypt and Assyria] turn to God and faithfully worship Him, He might even place them ahead of ethnic Israel. As it is written: «.. THEY [THE EGYPTIANS] WILL TURN TO THE LORD, AND HE WILL RESPOND TO THEIR PLEAS AND HEAL THEM… The Egyptians and the Assyrians will worship together. IN THAT DAY ISRAEL WILL BE THE THIRD [NOT THE FIRST! ], ALONG WITH EGYPT AND ASSYRIA, [and this will be the sign of] a blessing in the midst of the Earth; THE LORD ALMIGHTY WILL BLESS THEM, SAYING: “BLESSED BE EGYPT MY PEOPLE, ASSYRIA THE WORK OF MY HANDS, AND ISRAEL MY INHERITANCE”»- Isaiah 19: 22-25.
Notice how in the former verses the Creator describes Egypt and Assyria using words like, “my people”, “the work of my hands”. The keen reader will immediately be aware that these terms are also used elsewhere to describe ethnic Israel, as it is written: “Thus saith the Lord God of Israel, LET MY PEOPLE GO, THAT THEY MAY HOLD A FEAST UNTO ME IN THE WILDERNESS”- Exodus 5: 1. And also in another place: “Therefore thus saith the Lord, who redeemed Abraham, CONCERNING THE HOUSE OF JACOB: “JACOB SHALL NOT NOW BE ASHAMED… But when he seeth HIS CHILDREN, THE WORK OF MINE HANDS, in the midst of him, they shall sanctify My name... ”- Isaiah 29: 22-33.

«Reformed Samaritanism teaches that Torah (God’s Law) promises to those who stick to it that they will become heads, instead of tails. As is written: “ And the Lord shall make thee the head, and not the tail; and thou shalt be above only, and thou shalt not be beneath; if that thou hearken unto the commandments of the Lord thy God. .. ”- Deut. 28: 13, KJV). What does it mean? It means you will naturally develop a mind of your own [so that you will be able to “ruminate” each idea, thereby telling apart fact from fiction, and truth from wishful thinking]. And the former is the reason why, as a rule of thumb, 2 Hebrew believers will have no less than 3 valid opinions concerning any 1 (single) subject»
