The Supreme Court heard oral arguments Monday in a case about whether a custom webpage designer who disagrees with LGBT marriage can refuse to create a website for a same-sex couple if the service itself constitutes a form of compelled speech, diving into a range of wild and surprising hypothetical arguments by the justices.

The justices were hearing arguments in business owner Lorie Smith’s appeal seeking an exemption from a Colorado law that blocks discrimination based on sexual orientation and other factors after the U.S. Court of Appeals for the 10th Circuit ruled in favor of the state.
