I suspect it's a bit of a memeification of a more poignant quote by Aimé Césaire, which you've probably seen. The one from https://en.prolewiki.org/wiki/Library:Discourse_on_Colonialism

Yes, it would be worthwhile to study clinically, in detail, the steps taken by Hitler and Hitlerism and to reveal to the very distinguished, very humanistic, very Christian bourgeois of the twentieth century that without his being aware of it, he has a Hitler inside him, that Hitler inhabits him, that Hitler is his demon, that if he rails against him, he is being inconsistent and that, in the end, what he cannot forgive Hitler for is not the crime in itself, the crime against man, it is not the humiliation of man as such, it is the crime against the white man, the humiliation of the white man, and the fact that he applied to Europe colonialist procedures which until then had been reserved exclusively for [non-white peoples].

Treatlerite, by comparison, seems to imply that people are okay with genocidal Hitler-like policies mainly because they get treats out of it. Which reduces complex dynamics of class and caste contradictions to basic hedonistic drives.

The irony here is that Césaire was encouraging, in the words above, "to study clinically, in detail, the steps taken by Hitler and Hitlerism and to reveal to the very distinguished, very humanistic, very Christian bourgeois of the twentieth century". In other words, to put great detail effort into understanding just what the hell is going on with white people precisely, especially the bourgeoisie of them, and how insidiously they hide behind faux pro-social narratives.

And reading Indi's more recent articles makes me think Iran worked out precisely what would make the white bourgeoisie finally hurt and is going through a gradual process of making it happen: https://indi.ca/the-after-math/

But, similar to Russia's gradual, plodding advances in Ukraine, they are not in a rush. They don't need to make it all happen tomorrow. They only need to make sure that the trajectory keeps going down for the white bourgeoisie, that it is, in a sense, "a controlled explosion" as much as possible.

I think a similar understanding of the imperial core working class is needed and analyses of them often seem inadequate, from what I've seen. A framing like "treatlerite" doesn't elucidate much. Sometimes the implication made is that the treats are treating the symptoms of the awful conditions, but if that's the case, then it's not the treats themselves that are sought after, it's other needs and the treats are a coping mechanism; and if that really is a big part of what's going on, that means the imperial core working class are a lot closer to revolt than they may seem at a glance. But I don't think this explains all that much because having a means to treat symptoms does not explain the active support that many still have for the system and how it works.

One thing that repeats in my mind, is that it's vital to look at the internal caste-like systems of imperial core regions. Such as in the US, which, roughly speaking, goes down something like: white man, white woman, black man, black woman, indigenous man, indigenous woman

Is the white working class just a mini version of the white bourgeoisie in terms of racism, colonial practice? Or is it more complicated than that? I'd think the contradictions would have to make it more complicated. That the white working class is intentionally meant to be racist enough for the white bourgeoisie to recruit from them as needed, but their racism (in today's world) is often more of a passion-based racism than a plotting, logistics-based one. This makes a kind of sense to me because if the working class is good at logistics, they are harder to control, whereas passion alone can be directed via media and the like.

But I am only trying to expand the conversation, not do a comprehensive analysis.

It does have a real "vibes based analysis" ring to it. Its just a rehash of "bread and circuses" which was just moralizing against poor people for trading the "democratic" Roman Republic for food and entertainment from Ceaser. Its judging people for not giving up their own real comfort and security for the chance at a hypothetical better future, an act which has no precedent in history.

For the majority of people, they need to have nothing to lose before they sacrifice everything. That is the standard Risk analysis of the human mind aka. human nature.

Meh, I'm no fan of using the term in a serious context cause it's a bit juvenile but there's a reality to 'voting for new hitler if hes offering me PS5's and chocolate'

It's not really confined to the first world either, I see it all the time in my corner of the third world. The truth of the matter is most people are gonna be 'treatlerites' which is why those who are not 'treatlerites' (professional revolutionaries) have to come up with a plan to provide 'treats' (personal consumption) under a socialist order. The difference in strategy between the USSR and China comes to mind with this. Obviously subject to the prevailing conditions of whatever country we're looking at.

Recommend avoiding the word "denigrate" as it has racist origins.
