If you think the anti-colonial project is anywhere near complete, I'm dumbfounded. Are you just... not even aware of the existence of the Global South?
Your position is indistinguishable from badly-executed farce. Maybe you should study a lot more history and social science and spend a little less time being a pretend leftist on the Internet.
I'm not a Marxist communist, if that's what you mean. I think if you ask just about any actually practicing leftists of basically any stripe whether the age of Western colonialism has actually ended, you will be laughed at.
But it's clear that you are unlikely to understand what most of these terms mean, so I'll stop tilting at windmills and move on with my life.
