As Dr. Shahak points out and Ron Unz amplifies, honest Talmudic Jews make no bones whatsoever about their belief that the rest of us, the non-Jews, the goyim, were put on this Earth to be slaves and servants to Jews, and that we are little better than "beasts in the shape of men"
Agree. See previous point.

Yet Christians are highly tolerant of Jews, generally speaking, especially in the modern day and especially in America
True. Reminding you that the Talmud was signed some 1500 years ago. Christians at that time were anything but tolerant, until about 200 years ago.

the Catholic Church in particular has claimed that the Jews are God's chosen people and are a protected group, ever since at least the time of Pope Gregory the Great, who issued a Papal Bull in reaction to the persecution of Jews in Palermo that stated very clearly that Christians have a religious and moral duty to protect Jews
That's new for me. However somehow Jews were persecuted repeatedly and nothing of the sort helped them most of the time.

Ultimately, the question of what and how Jews worship is, of course, up to them. The problem is that so many of the Jews remain so ignorant of their own faith – and of how far the Talmudic orthodoxy has strayed from the actual, literally written-in-stone Word of God
You'll be surprised again, but I somewhat agree. Most Jews are secular and don't bother to study their religion and understand it.

Just to sum it up:
I believe some of what is written is incorrect. I may be off, as my understanding may be lacking. Judaism is not polytheistic, but houses divine entities, both good and bad as well as good and evil.
As per redemption and salvation – I believe (and it is my belief) that a great reform of Judaism will come, but probably only in the next generation.

Spells, curses, magicks, and various other forms of jiggery-pokery are actually quite common to Talmudic Judaism

Correct. The Talmud was signed (=finalized editing) about 1500 years ago. At that time those were part of Judaism. Not proud of it, but it is part of my religion. Guess what? It is also part of Christianity till not that recent. Don't see the problem.

Incidentally, I have never quite understood why Jews insist on giving God an actual name. In the New Testament, at least the bits of it that I have read, the name "Yahweh" doesn't come up at all

Misconception. God's name is unknown and is comprised of 42 or 72 letters. "Yehowah" means is Hebrew "Who he is". "God said to Moses, “I AM WHO I AM,”" (Exodus 3:14). "Yehowah" is a derivative of Being.

If one of my readers might be inclined to explain to me just why it is that Jews call their version of the Lord "Yahweh" or "Jehovah", rather than "the Lord", "the Father", or simply "God", as Christians do, I should be much obliged.)
Again, misconception. We call our God many "names" – The Lord, God (in Hebrew it is plural word – ELOHIM or Elokim) , He who is Blessed (HAKABA). No one in their right mind today uses "Yehowah", unless he or she wants to shock the audience.

Indeed, judging by the polytheistic nature of actual Talmudic Judaism, and the fact that it is so obsessed with ritual and superstition, I am forced to conclude that this particular strain of Judaism is really a lot more like Hinduism than it is the religion described within the Old Testament.
I understand why you think so, but it is wrong. It completely unlike Hinduism (know a little bit about it). Judaism is not polytheistic in any way.

Among large portions of the faithful, the Talmud is supplemented by the Kabala, another large collection of accumulated writings, mostly focused on mysticism and all sorts of magic
That's a miss conception. The Kabala explains the world in mystical terms and provide "esoteric" know-how. The Talmud is a "set of rules" based on case studies and interpretations. They, most of the time, complement and not supersede.

Such Jews do not worship a monotheistic God, but instead actually worship a number of different entities, both male and female
That is a long time argument. The main core believe of Judaism, which is based in one of our oldest "battle cry"/"identification" is " Hear, O Israel: The LORD our God, the LORD is One " (Deuteronomy 6:4). It is confusing that Judaism acknowledges divine entities, both male and females, as well as good and evil. You sometime "acknowledge the devil" (Literally). This is usually to avoid consequences in a specific context or in order to help a poor soul. There is n worship in the Kabala, but there are instances in which one may use devils (highly not recomeded).

Obedience to ritual is far more important than understanding the point of those rituals
Correct. The origin is Mount Sinai sighting of God. "All the words which the Lord hath spoken will we do" (Exodus 24:3). The Hebrew phrase for this is "Na'aseh VeNishma" which means "We shall do (first) and then listen (understand)". In Judaism you sometimes do not know WHY, but you still need to practice.
