This is what detractors say but it is never substantiated as a criticism. By what natural law of capital is it so ubiquitous that a revolutionary proletarian class must exist among colonizers?

Where did this "revolutionary" come from? You are putting words in my comments where it does not exist. Interesting how you complain about strawmen and begin your comment with one. I am not a "detractor" of J. Sakai's work, I mentioned several times that there's value in it, but a critical reading is definitely essential. So that I can "substantiate" my criticism, here is an excerpt from the very first chapter :

When we point out that Amerika was the most completely bourgeois nation in world history, we mean a four-fold reality: 1. Amerika had no feudal or communal past, but was constructed from the ground up according to the nightmare vision of the bourgeoisie. 2. Amerika began its national life as an oppressor nation, as a colonizer of oppressed peoples. 3. Amerika not only has a capitalist ruling class, but all classes and strata of Euro-Amerikans are bourgeoisified, with a preoccupation for petty privileges and property ownership the normal guiding star of the white masses. 4. Amerika is so decadent that it has no proletariat of its own, but must exist parasitically on the colonial proletariat of oppressed nations and national minorities.

"most completely bourgeois nation", "bourgeoisified", "Amerika (...) has no proletariat of its own". Sakai uses Marxist terms, but how they are used are completely meaningless. What "bourgeoisify" means? How come Amerika has no proletariat of its own? The country is still an industrial powerhouse, it's a producer of commodities as well, therefore it has proletarians producing these commodities. Even slaves to that point, which consists of 60% of the prison population which are obliged to work for several corporations of different economic sectors.

I am making a reasonable critique of this work from a Marxist standpoint. If you can only see "strawmen" and "white fragility", I'm sorry, you are possibly projecting a white fragility or white guilt onto others, because I'm not even white by your standards. For all intents and purposes, I am disgusted by white people in United States. I've seen the shit white women (karens) in this awful country do, it's frankly terrifying. But I am a Marxist, I understand that these people were not at all born this way, they are conditioned by their environment, by white supremacist bourgeois ideology, and that treating them and the ideology that affects them as one and the same is the purest sample of race essentialism.

Under the Nazi Germany, the most vile racist chauvinism was promoted as state ideology, and genocidal rapist campaigns of terror were promoted throughout the whole Europe. Yet, Stalin in 1942, in the midst of an war, said:

It would be ridiculous to see in the Hitlerite clique the German people or the German state. Historical experience proves that Hitlers come and go, but the German people, the German state, remains. The strength of the Red Army resides in the fact that it doesn’t nurture, nor could it nurture, any hatred toward other people, and therefore couldn’t even nurture hatred for the German people; it is educated in the spirit of the equality of all peoples and all races, in the spirit of respect for the rights of other peoples.

Nowhere a Marxist would declare a whole people, and even, the majority of the Statesian people as irredeemable to the point they would claim it is useless to work with them. The white people of the US are captured by bourgeois white supremacist ideology, and instead of self-defeating themselves, all revolutionaries should devise strategies and enhance their agitation and propaganda to fight against this ideology, an effort led by the oppressed ethnic groups. Fighting white supremacy does not mean fighting Statesian white people.
