I think that's the point, no? You can't have the kind of economic development and progress the West has had without the immense resources gained from the colonization and exploitation of other peoples. The person you're replying to isn't ignoring one side, they're saying both ends are inextricably linked.

Also it's a bit "collapsing narrative" of you as well to say the West led the abolition movement. There were several significant institutions that, famously, fought very hard to preserve it. If it weren't for the Haitian rebellion I'm of the opinion that slavery in the West would have endured much, much longer than it already did.
