So you think minorities tend to be treated fairly, and complaints about racism and prejudice are mostly without merit? Not just in the US, but globally, e.g. in India [1], China [2], or the Middle East [3].
Or do you think that whites will be the exception? While other minorities were maligned preceding their persecution, whites are showered with universal praise, so there is no resentment or animus they should fear from any group, now or in the future.
