Amy K. Hall of Stand to Reason explains what the case is really about:
Today, the Supreme Court will hear arguments in the Masterpiece Cakeshop case. I recommend you read this article by David French to clear up a major misconception about the case that’s being promoted out there. The article responds to a New York Times opinion piece that completely misunderstands the case, claiming it’s about denying people services “because of who they are.” (See here and here for more responses to this common mistake.)
