It isn’t.
Systemic discrimination refers to patterns of behavior, policies, or practices that are part of the structures of institutions and that result in unequal outcomes or disadvantages for certain groups—typically based on race, gender, age, disability, sexual orientation, or other identity markers—even if no individual actor is explicitly biased.
There is no pattern, policy or practice that is discriminatory.
There is a law which allows for discrimination and one case of discrimination. That isn’t a pattern.
You may say “well the policy allows for it!” The policy isn’t discriminatory. It’s not telling people to discriminate.
Anyway, the law sucks.
