Glenn Youngkin was elected Virginia’s governor in large part because of the uproar over extremist ideologies that promote racial division under the guise of “antiracism.” But what can he do about the problem? The first step is simple: Prohibit the use of “diversity, equity and inclusion” statements in any state government or government-funded agency. The anger about critical race theory in schools reflects a larger frustration. In the past two years, the diversity regime has hardened. Its proponents have adopted more-strident rhetoric. Some speak openly of quotas. The range of permitted opinion has narrowed.
