Patsocs have a weird fixation with financial capital as opposed to industrial capital, but regardless where did that capital in the US come from? From settler-colonialism.
They argue against this by saying essentially that the colonisation of the US has been realized and so you shouldn't focus on it because it's impossible to undo it at this point. This is the same position basically all communist parties in the US hold as well.
But this is not true because there's basically nothing different between "Israel" and the United $$naKKKes of AR-meriKKKA (couldn't resist lol). Genocide is still ongoing in the US, and we can point to many events that still show this to be true but I think the most famous one in recent memory is the Dakota Access pipeline. There's a reason it went through native land and not through a nice white neighborhood.
I think decolonization takes a lot of characters, as varied as colonialism is. The decolonization of a 400-year project has never been done before, so we're treading uncharted territory here. I don't think that "lack of prior practice" is a valid reason to say welp, let's just forget about this and do what we know instead.
