In this case: basic and functional equality of the members of a society. Like pornography, this is hard to define precisely, but I know when the violations are egregious enough, and the functional equality of black Americans through in the eyes of the police right now is certainly egregious enough.
Police brutality of black Americans is simply and factually not relevant to the business of every company.
Insofar as it represents a fundamental and existential inequality in society, it certainly is.
Really not. Many businesses are not impacted by inequalities in society.
