As a Klanadian (little different), the average settler-Klanadian can at least recognize that their grocery store, their neighborhood, their entire country is built on stolen land whose theft sustained through consistent lowkey genocide. Some people can recognize how fucked that is (increasingly more, at least). Others will wring their hands, look the other way, and pretend they feel bad about it but "it is what it is" now (while harboring plenty of racist biases, etc). Others still will be actively supportive of retaining their hateful status quo, and a portion of all three demographics will engage in perpetuating it in one way or another, because that's how their bread is buttered, if nothing else.

Same goes for AmeriKKKa, and same goes for the racial hierarchy and divide-and-conquer system across the west, the imperialist economic systems that sustain the west, etc. It's easy to claim innocence, right up until the colored peoples (as an Asian myself) are becoming "competition," right up until material, or even just social equality (nevermind even reparations to this group or that, or to the entire countries and nations lying in ruins, or the return of stolen goods) is brought to the table.

Not saying all Americans/white westerners are guilty, hell, the majority are varying degrees of ignorant as you describe and many are also genuinely innocent and appalled by the system. Liberals though certainly are exactly just as asg101 described though (those that aren't, don't remain libs for long), and for the rest- well, while I think there's truth to what you both say, obviously and sadly I think it leans more in the negative direction, especially when push comes to shove.
