LegalZoom wrote an article about whether businesses can refuse service here: https://www.legalzoom.com/articles/the-right-to-refuse-service-can-a-business-refuse-service-to-someone-because-of-appearance
They wrote that "a baker refused to create a wedding cake for a same-sex couple, saying that it violated his religious beliefs. The court held the baker liable, saying that his reason was just a pretext for discriminating against gays."
But in the same article they state "the federal law does not prohibit discrimination based on sexual orientation, so gays are not a protected group under the federal law."
So "the pretext for discrimiating against gays" is a non sequitur because it doesn't exist.
But they wouldn't give the details about what case it was. If they were talking about Masterpiece Cake Shop v. Colorado Civil Rights Commission they got it totally wrong...
Is LegalZoom wrong?
