I don't know what people hold in their hearts, but I think the arc toward fairness and equality is indicative that as a society we are progressing. If there is a western worldview, then I think it must show up in our politics where economic reform is lacking and social reform moves forward, but we all know that on the economic front there are corporate interests in the way of what most people actually want. Our systems have disconnected us from the world, but this is not a purely western phenomenon as we see it in all industrialized nations.
Decolonization in its literal form is giving back the land and allowing independence. It reverses colonization. What you are referring to sounds a lot like anti-racism, which I agree with. Ending systemic inequality will be a long struggle because it can be hard to identify and it requires literally everyone to do it.
Where I think we are going to have a problem with decolonization, especially in BC, is the acknowledgement that we are on their land. This has legal implications down the road and it creates animosity because the reciprocal consequence of that statement is that non-indigenous people don't have a land or a home that is truly theirs. Reconciliation is the restoring of friendly relations, and we have both talked about moving forward together, so the concept of decolonization is going to be difficult to square with that goal. What is the process that makes this everyone's home and not a country full of guests? Most of the First Nations in this province have no interest in settling these claims.
