On Monday, the Supreme Court heard 303 Creative v. Elenis, a case brought by a Colorado designer who only will create wedding websites for opposite-sex couples—not same-sex ones—and wants to advertise that fact, just like brick-and-mortar businesses once hung signs announcing whom they would refuse to serve. After arguments, it appeared clear that the 6-3 conservative majority is ready to use the case to undermine civil rights laws that secured equal access to goods and services for all, by carving giant loopholes that would allow businesses to, once again, boldly turn away clients based on who they are. Will there be any limits if the court allows businesses to refuse service to people their owners dislike? During the arguments, the court’s three liberal justices focused on whether a new wave of legally-permitted discrimination would just target LGBTQ people, or whether an opinion in favor of LGBTQ discrimination would logically also open the door to discrimination based on other statuses such as race, religion, sex, disability, and national origin.
