It couldn't be clearer in the Charlie Craig and David Mullins V. Masterpiece Cakeshop case, which the Supreme Court will hear soon.
Back in 2012, the plaintiffs went to the defendant's bakery to have a cake for their wedding, which owner Jack Philipps refused, citing religious reasons. Craig and Mullins complained before the Colorado Civil Rights Division, which agreed with the couple in 2014. They even ordered that the bakery completes "extensive sensitivity training". After Philipps failed to have the Colorado Supreme Court hear his plea, he appealed to the United States Supreme Court, which agreed to take on the case.
So-called civil rights groups like the American Civil Rights Union stand with the plaintiffs, saying that "when businesses are open to the public, they're supposed to be open to everyone." Gay webzines like the Gaylygrind automatically call the defendant and his supporters "anti-LGBT hate groups." Even Libertarian Party candidate Gary Johnson wants him to "bake the cake."
