Should bakeries be required to make wedding cakes for gay couples?

In December 2017 the U.S. Supreme Court began hearing arguments in the Masterpiece Cakeshop v. Colorado Civil Rights Commission case. In 2012 Charlie Craig and David Mullins asked Colorado baker Jack Phillips to make a wedding cake for their wedding. He refused to bake the cake and said doing so would clash with his religious beliefs. The couple said they were humiliated and filed a complaint with the Colorado human rights commission. Proponents of the couple argue that business owners should not be able to discriminate against customers based on their sexual orientation or religious beliefs. Proponents of the baker argue that business owners are private citizens who must be protected by rights that ensure religious freedoms.
