"Explicit white nationalism is surely the most aggressively marginalized ideology discussed here. As we have seen, advocating racism is perhaps the fastest way for a politician, pundit, or public intellectual to find himself or herself a social pariah. That being the case, there is little chance that transparent white racism will again become a major political force in the United States in the immediate future. However, the fact that antiracists on the right and left are extraordinarily vigilant in their effort to drive racists from public discourse can be viewed as evidence that they believe such views could once again have a large constituency, should racists ever again be allowed to reenter the mainstream public debate. Whether their fears in this regard are justified is impossible to determine at this time. What we should remember, however, is that the marginalization of the racist right in America was largely possible thanks to cooperation from the mainstream conservative movement, which has frequently jettisoned people from its ranks for openly expressing racist views. If the mainstream conservative movement loses its status as the gatekeeper on the right, white nationalism may be among the greatest beneficiaries, though even in this case it will face serious challenges."
