“Antiracism” permits many people to practice racism vicariously by adopting the cause of every race but their own.
In this quote, Robertson seems to be defining racism as a “preference for one’s own ethnic people group.” I presume that because Robertson talks about racism as “adopting the cause.” I only note this because so often in conversations about racism the word is left undefined. Robertson has defined it for us here and in doing so has also informed us that “racism” is an inescapable category. Per Robertson, if you are not adopting the cause of your own people you are, by default, adopting the cause of those who were formerly not your people but who are now your people because you have adopted their cause.
Think of those people who are advocating for more immigration or for amnesty or open borders. Think of those voluntary agencies that help relocate putative refugees and are so often tied to Church organizations. In that advocacy, those people have not avoided being champions for a particular race and they have not avoided being racist as against a particular people. They have not shed themselves of “racism.” Instead, they have taken up the cause for the stranger and the alien as against their own people. They have determined to render an inheritance to the stranger as opposed to their own children. What they have not done is eliminated their own ethnic bias. They simply now are biased against their people and are biased for those who are displacing their extended family. They have gone from an ethnic bias for their people to an ethnic bias for the stranger and the alien.
