I am critiquing from a Marxist perspective, of which Decolonialism is a large part. "Hexbear consensus" doesn't really exist because hexbear is a mish mash of competing ideologies
This is inherently a settler nationalist movement, inherently reactionary. You are on stolen land, settled land. Inventing false nationalisms that have its roots in white supremacy is not decolonialism, it is just a different outlet of that nationalism. It is inherently a petite bourgeoisie kind of nationalism (thus a petty nationalism).This is like being a Texan nationalist, a Californian nationalist, a Quebec nationalist, Deseret, etc. You have still a colonial type of nationalism. The people who truly own the land and from which it was stolen still exist, they exist within 'cascadia' and will be oppressed within it no matter what flag changes.
It is not coming from the oppressed peoples, but comes within a white petite bourgeoisie nationalist character. You disguise this by saying "oh well we fight for the workers, we fight against the US" when its less like New Afrika and more like the Boer sepratists. Oppressor Nationalism. "Cascadia" will be an enemy of anti-colonialism just like the US.
