In general, suspect classes (which can also be called protected classes, because, again, this is an area where courts have decided, “Let’s wing it”) are groups that can be labeled by their race, religion, national origin, or immigration status. Some argue that being “historically singled out for discrimination” is key to the classification. Some argue that people of a “discrete and insular minority” should be considered members of a suspect class. Others think that the classification should be given to people based only on “immutable characteristics.”
