ABSTRACT: The paper examines the clash between public accommodations laws and freedoms of speech and religion in America at the light of the recent decision of the U.S. Supreme Court Masterpiece Cakeshop Ltd., v. Colorado Civil Rights Commission. The case deals with the refusal of a Colorado’s bakery to provide a wedding cake to a gay couple based on the owner's religious beliefs. After explaining the decision of the Court and the position of the U.S. Supreme Court Justices in their dissenting and concurring opinions, the paper addresses the claim of freedom of speech and of the tolerance principle in the pluralistic age.
