You may be in the presence of mere virtue-signalers if they:

• wring their hands about police brutality without ever calling for repeal of all victimless-crime laws, which create a poisonous dynamic between police and public precisely because the conduct being policed is consensual for each party to the illegal transactions;
• bemoan the lack of growing black-family wealth without calling for the elimination of Social Security, which imposes a regressive tax to confiscate savings that would otherwise be heritable by the savers’ children;
• lament the inadequate economic mobility of people in minority communities without condemning occupational licensing, which prohibitively raises the cost of entry into many kinds of work;
• condemn the inadequate economic mobility of people in minority communities without opposing zoning and other land-use controls, which inflate the price of housing in areas with superior economic opportunities;
• decry the sad state of education for minority children without demanding parental choice in an entrepreneurial free market in schools;
• denounce minority unemployment without acknowledging that the legislated minimum wage kills jobs for people with the least skills and makes the surviving jobs more onerous than before.
