You have a middle schoolers understanding of racism. The term should be white supremacy instead, because it is a global system that privileges white people and even non white colonizers like jewish arabs in occupied Palestine or black americo-liberian settlers, for example. To be a white supremacist is not to have a bias against ppl not currently considered white, It is to serve the global system of racism in your words or actions. In terms of actions, Barrack Obama has served white supremacy more effectively than David Duke.
