I just think it should not come across as surprising that a Honduran considers Honduras a western country

If they are a communist and understand history of colonialism then they wouldn't see themselves as western nor would they want to see themselves as western. They would see their country as "westernized" by outside, imperialist forces - and they must decolonize and "de-westernize"

That it would be more productive to point out that class relations within Honduras supersede such cultural ties, instead of antagonizing him with how much a northern european would not consider him western.

It's not "antagonizing" someone to just plainly and clearly state the truth of their peripheral status and that the imperial core would eat them alive in a second if they felt like it. Any allegiance or camaraderie they feel with "the west" is entirely one-sided and in their own mind and they must be disabused of this fantasy. Pathetic for any communist to really hold these views, makes it sound like they would be little different from their comprador masters in practice - trying to suck up to the west for membership still, still being good house slaves and running dogs. I only trust people who hate the West, want to distance themselves from it, destroy it, and purge it from their societies. Wanting to be included in "the West" to me is basically class treason, especially to start making white supremacist adjacent argument about how "The West" means Ancient Greece, and there's nothing inherently racist about the Greeks so modern day "West" also isn't racist just another grouping of peoples.

This is chauvinistic delusion that any communist should be ashamed to think. Then to try and shame us for being racist when they have so internalized Western white supremacy is another layer on top.
