In light of the discussions concerning Indiana's law... There is a very interesting article in the Cornell Law Review Volume 49 Issue 2 Witer 1964 entitled "Freedom of Choice in Personal Service Occupations Thirteenth Amendment Limitations on Antidiscrimination Legislation". Basically the 13th Amendment says that a person can not be forced into involuntary servitude. Forcing some to perform a service against their will even if compensated may be argued to be involuntary servitude. We are a country of laws and rights. Sometimes there are competing rights which calls for the courts to sort out. The new law in Indiana is no exception.
