Idolatry always leads to human sacrifice because to prove your idol more important than the human soul the natural test is to sacrifice a human in the altar of the idol.
This is nonsense. You are pulling this from nowhere. I'm sure we could find some sun worshippers or nature worshippers who don't sacrifice any humans.
Also, this whole post reminds me of Sherlock Holmes style deductions. You know, the one where the detective says something that's mostly right most of the time, then makes a deduction based on something else that's mostly right, until he has a dozen links in his chain of reasoning and the compounded error rate for all those mostly correct steps means the detective could not realistically exist. You are connecting a lot of things that are mostly correct, to the point where your conclusion is worthless.
"I'm sure we could find some sun worshippers or nature worshippers who don't sacrifice any humans"
I am sure of the logic of sacrifice in all cultures: it is how you commit to the belief. In paganism, the world is full of spirits, while Judaism cleaned the world of spirits (not totally, evil ones were still supposed to exist) and forbid any cult to them: it was an early and radical disenchanting ideology.
Of course, nothing is free: monotheism moved sacrifice from the religious to the political realm: from the altar to the battlefield. I prefer the ocassional political/judicial sacrifice of monotheism over a world of spirits that can be angry and demand habitual appeasement.
Now, this is only the introductory paragrapah: the purpose of the text is to identify the modern phenomenon of political idolatry with the (often bloody) worship of essentialist identity.
Even a radical nationalism is not an idolater if he tries to maximize the welfare of the national group. But it is never like that. They are allways happy to sacrifice the nationals for the Nation. The collective subject is an Idol with its own desires and independent existence. The canonical case, of course, is Dugin: the most conscious of Aztec High Priests. He is absolutely rigth: to conjure the nation into existence an Holocaust is necessary: either you feed the God, or it dies.

You are trying to argue with the real world.
I know that idolatry doesn't lead to human sacrifice, because there are actual idolators who don't sacrifice humans. You are just saying "yes it does". No it doesn't. It's not hard to check the real world and see if your pronouncements match reality. They do not.

"By delving into ethnographic records, the researchers tried to tease out the relationship between human sacrifice and social hierarchy. They find that the prevalence of sacrifice increased with the degree of social stratification: it occurred in 25% of cultures with little or no stratification, 37% of those with moderately stratified societies, and 67% of those that had a pronounced hierarchy."
Human sacrifice is essential for the construction of large agrarian societies. Now, what percent of the 33% of hierarchical societies that do not practise human sacrifice are Abrahamic? It is true that the statement is not "true" in general, but is true enough for the case of "hierarchical societies", that is, those with complex political arrangements.
Now, what percent of the 33% of hierarchical societies that do not practise human sacrifice are Abrahamic?
This is like saying "I think that Rhode Islanders are all murderers. What percentage of the people that do not murder are from Rhode Island?" This is illogical; the reasoning is backwards.
Do you think that Japan is a hierarchial society? Do you think that Japan performs human sacrifice?
Idolatry is the worship of non-conscious objects, sometimes falsely attributing consciousness to them, sometimes putting the value of some admittedly nonconscious being over that of conscious beings. Idolatry leads to human sacrifice because to prove your idol more important than the human soul the natural test is to sacrifice a human in the altar of the idol. That is precisely why Judaism was founded on the prohibition of idolatry and human sacrifice.
When the religious idols of the past were weakened, political idolatries substituted them. Race, nation and the working class were given intrinsic reality and value. Let’s be clear: I am absolutely for sacrificing yourself or even others for an idea, if in the other side of the idea there are real humans improving their happiness and potential. If the flag, the party, or the ideology serves the people, sacrifice is not idolatry, but martyrdom. But conscious beings must only sacrifice for other conscious beings because nothing in this world is higher than us.
For a few decades after the second World War, this idea was almost universal. Different branches of humanism fought often cruel wars, but always under the banner of a better tomorrow. Those happy days are over.
The fear of death, the feeling of disenchantment toward a world where there is not more guide than your own mind has conjured back the political and religious demons of the past. Mind is real and conscious, but mortal. The human longing for eternal existence is the natural portal for the smuggling of idolatry: a rock, a tree or some arbitrarily defined tribe (nation, race, even gender) can outlast your life, so it is natural to put those trivial but durable objects over the daily miracle of (mortal) consciousness.
But nothing really exists but you (your conscious mind, your cartesian self, your res cogitans) and other conscious beings. The public life is instrumental: the government, the flag or the garbage collection service are necessary, and consequently worthy of the sacrifice of blood and treasury, but their value is to make the private life possible. It is in private life where we find what matters: romantic love, family life and the quest for knowledge, enlightenment and creation.
The price of discarding superstition is accepting that the meaning of existence is not something we have to search for, but something we create. The humble utility function in the Economics textbook is in fact a massive metaphysical burden that every intelligent being must cope with. What do I want? Adam was given by God the task of naming the world, and we have inherited the task of putting value on it. The task is massive, and freedom is often seen by moral weaklings as the ultimate slavery. We end up hating our reason and desire. As Jacob, we wrestle with God’s angel, with our own image.
But the only alternative to freedom and reason is self-mutilation. I read “Memoirs of Hadrian” in my early twenties, and I knew that I had read the only self-help book I would ever need; what else can you do with your life but a work of art? A work of art is not made of truth (while it shall respect truth), but of will and desire.
Sometimes, of course, you can feel disenchanted, and of course you can always find some shaman, offering you comfort at the modest cost of your soul now (probably of your blood tomorrow). The race of Baal worshippers is inexhaustible: esoteric nationalists (René Guénon, Julius Evola, Alexander Dugin), religious totalitarians (Sayyid Qutb, Edmund Waldstein) and race and gender critic theorists (Theo Goldberg, Andrea Dworkin) are irredeemable enemies first of Truth, then of Mankind. Politics is as complex as the problems of society itself, and there is room for massive disagreement, but many political ideologies are idolatry, and we can effortlessly reject them.
