It's Legal: If not readily apparent, the legality of something says nothing about its morality. If being legal made something moral, then activism and social justice would be immoral, because to fight against what is legal would mean to fight against something which is moral. We couldn't judge our slave owning ancestors for their immorality because they were living within the law. We couldn't judge the Japanese internment camps we had in the U.S., the child separation policy with illegal immigrants now, the genocides committed by various governments, etc. Governmental law is descriptive, not necessarily morally prescriptive.
