Racism is broadly defined.
From normal instinctive discrimination to overtly aggressive discrimination.
So please be more specific.
It could be said that all governmental policies that are designed to bring about social order or a change in social order, are based upon some level of discrimination.
So for example, the immigration policies of any government that seeks to protect a nations established sovereignty and assets, are based upon discrimination.
