Actions may be legal, or they may be illegal. Whether they are moral or not is a totally separate question. (When the law is wrong, lawbreaking is the right thing to do.) But while actions may be illegal, people are not. A person's existence and life and worth aren’t reducible to the papers that they carry or the legal or political status that they have. If you’re talking about people that way, you ought to consider talking about them a different way. Referring to women or men or children or human beings by their legal status alone is dehumanizing and insulting to them; it is also coarsening and brutalizing for the person doing the referring. It encourages the worst in those who do it, and it justifies inhuman reactions toward those that it is done to. No human being is "illegal."
